High contrast demonstrations with the vortex coronagraph

2014 IEEE Aerospace Conference, 2014

The optical vortex coronagraph (OVC) has great potential both for carrying out high-contrast exoplanet searches around nearby stars, and for reducing the size of the space telescopes needed for exoplanet imaging and spectral characterization missions. This is because using a coronagraphic mask to modify the phase of a focal-plane stellar point spread function, instead of its intensity, leaves transmissions high ...

  • High contrast demonstrations with the vortex coronagraph

    The optical vortex coronagraph (OVC) has great potential both for carrying out high-contrast exoplanet searches around nearby stars, and for reducing the size of the space telescopes needed for exoplanet imaging and spectral characterization missions. This is because using a coronagraphic mask to modify the phase of a focal-plane stellar point spread function, instead of its intensity, leaves transmissions high even at small angular offsets from the center of the mask. Here we discuss recent progress in demonstrating the capabilities of the OVC, including the production of vector vortex phase masks, and recent contrast measurements obtained for optical vortex masks in the Jet Propulsion Laboratory's High Contrast Imaging Testbed (HCIT). Specifically, monochromatic contrasts below 10-9 have recently been demonstrated across wavefront-corrected “dark hole” regions extending from 2-7 λ/D from a laboratory simulated “stellar” point source, where λ is the wavelength, and D is the aperture diameter. Initial broadband (10% bandwidth) contrasts are not far behind, at approximately the 10-8 level. Further work is aimed at deepening and broadening wideband contrasts in the dark hole. It is anticipated that further development of broadband vortex phase masks should be able to provide the capabilities required by future space-based coronagraphic instruments aimed at exoplanet imaging and spectroscopy.

  • The Low-Frequency Radiotelescope NenuFAR

    NenuFAR (New extension in Nançay upgrading LOFAR), is a low-frequency SKA pathfinder presently in construction and commissioning in Nançay (France) [1], [2]. NenuFAR consists of 102 mini-arrays (MA) of 19 dual polarization antennas each. 96 MA cover densely a disk (core) of 400m in diameter, and 6 MA are located at distances up to ~3 km. NenuFAR will cover the range 10-85 MHz, that encompasses the low-frequency range of LOFAR ([3] 0-80 MHz nominal, that can be extended to 10-85 MHz), and be three instruments in one: (i)the core, connected to the receivers of the French LOFAR (FR606) station, will form a giant LOFAR station that can replace the LOFAR FR606 LBA field and be used as part of LOFAR; this LOFAR Super Station (LSS) will improve the sensitivity of long baselines by over one order of magnitude and thus the quality of high angular resolution (sub-arcsecond) imaging at low frequencies with LOFAR. (ii)the core will simultaneously be a standalone compact beamformer providing high instantaneous sensitivity, that will allows us to search efficiently for weak unresolved sources such as pulsars, exoplanets, stars ...A dedicated pulsar/time/frequency backend is in development, and the possibility to connect a SETI receiver that will analyze all NenuFAR data in piggyback (commensal) mode is under study. (iii)finally, thanks to the addition of a GPU-based correlator, NenuFAR will also (and simultaneously) be a standalone imager that can be used in two modes: a fast (1 sec) coarse resolution (1°) mode, using the 96 MA of the core only, and a slow (6-8 hours) medium resolution (~8') mode using all the 102 MA, core + distant; this mode will enable imaging studies in cosmology (search for the dark ages / cosmic dawn signal), planetary and stellar physics (exoplanets, stars and their plasma interactions), and the study of galaxies, clusters and haloes.

  • Adaptive filter based on NARX model for atmospheric noise removal on exo-planet observations

    In Digital Signal Processing, adaptive filtering is capable of dealing with random signal noise or time-varying signal. This paper presents an approach to create a NARX-based adaptive noise filter to remove atmospheric noise from astronomical signals. We use data obtained from the transit spectroscopy exo- planet observation, data was prepare using k-means clustering method of vector quantization, using the signal light coming from the star 1214 GJ Exo-planet GJ 1214b and a reference signal light curve based on Mandel and Angol model.

  • A Map-Reduce Model of Decision Tree Classifier using Attribute Partitioning

    Data mining is a process of analyzing data to extract the patterns in large datasets in the field of artificial intelligence, machine learning and statistics. Decision tree is one of the well-established classification models in data mining. The size and dimensionality of the data of today's world are increasing exponentially, thus finding of informative patterns is an important and crucial task. The organizations require distributed systems for storing and processing huge amount of data. The proposed method is the parallel implementation of Decision Tree methods based on the idea of attribute partitioning, where dataset is partitioned into multiple subsets of dimensions. We develop a Map-Reduce programming model for processing data using decision tree classifier based on attribute partitioning. The experimental results show an improvement in classification accuracy as compared to a traditional decision tree method.

  • A combined linear programming-maximum likelihood approach to radial velocity data analysis for extrasolar planet detection

    In this paper we introduce a new technique for estimating the parameters of the Keplerian model commonly used in radial velocity data analysis for extrasolar planet detection. The un known parameters in the Keplerian model, namely eccentricity e, orbital frequency f, periastron passage time T, longitude of periastron ω, and radial velocity amplitude K are estimated by a new approach named SPICE (a semi-parametric iterative covariance-based estimation technique). SPICE enjoys global convergence, does not require selection of any hyperparameters, and is computationally efficient (indeed computing the SPICE estimates boils down to solving a numerically efficient linear program (LP)). The parameter estimates obtained from SPICE are then refined by means of a relaxation-based maximum likelihood algorithm (RELAX) and the significance of the resultant estimates is determined by a generalized likelihood ratio test (GLRT). A real-life radial velocity data set of the star HD 9446 is analyzed and the results obtained are compared with those reported in the literature.

  • LEDs for less

    In 2012, there will finally be a first-rate LED bulb you can afford. In any case, this year you will for the first time be able to afford an LED bulb that's clearly superior to a CFL. It will give off a nice warm glow, work with your dimmer switch, use energy frugally and when you finally replace it after 15 years, you can just throw it in the dustbin. By then, you'll struggle to recollect what the letters "CFL" ever stood for.

  • In search of alien worlds

    In order to hunt a key component for planets like our own, astronomer Francesco Pepe will use the fiber to feed star light into a new detector-the High Accuracy Radial velocity Planet Searcher-North (HARPS-N), an ultraprecise spectrograph that is being assembled nearby, not far from a field of grazing horses. In the coming months, Pepe, an astronomer, and his colleagues will take apart the go-cart-size instrument, box up the pieces, and put them together again in a room near Italy's Telescopio Nazionale Galileo on La Palma, one of the Canary Islands. When HARPS-N begins observations in April, astronomers expect it will be the most precise planet hunter in the northern hemisphere. They also reckon it will be particularly well placed to help bag the most coveted extrasolar quarry of all-planets small enough to have rocky surfaces and cool enough to have liquid water.

  • Optimal band for extra solar planet detection: Sub-millimeter spectral region

    Most of the research on the exo-solar planet detection in the last 20 years concentrated first on the visible and then the IR region. The technology developments there were most pronounced, especially in terms of the telescope fabrication. We propose the sub-millimeter region where the signal to noise ratio is 1000 times more favorable than in the visible. We propose to place the observatory on the far side of Moon, where the stray-light noise from the Earth, near-Earth objects, and the Sun will be avoided.

  • The Kepler Mission: Zeroing in on habitable Earths

    NASA's Kepler Mission was launched on March 6, 2009 with the goal of determining the frequency of Earth-size planets in the habitable zone of solar-like stars using the transit photometry method. Kepler's driving design requirement was the ability to detect the 84-ppm change in brightness as an Earth-size planet transits its host star. As such, stability of the instrument and continuity of the data are keys for success. Kepler is beginning the third year of the planned 3.5 years of data collection and has already revolutionized the field of extrasolar planets, detecting over 2,300 planet candidates, the first Earth-size planets, the first circumbinary planets, and over 360 multiple-planet systems. The project has proposed an extension of the mission to NASA so that Kepler can continue collecting data and results for another four years.
