Direct Exoplanet Detection Using L1 Norm Low-Rank Approximation
Hazan Daglayan, Simon Vary, Valentin Leplat +2
We propose to use low-rank matrix approximation using the component-wise L1-norm for direct imaging of exoplanets. Exoplanet detection by direct imaging is a challenging task for t…
Low-rank plus sparse trajectory decomposition for direct exoplanet imaging
Simon Vary, Hazan Daglayan, Laurent Jacques +1
We propose a direct imaging method for the detection of exoplanets based on a combined low-rank plus structured sparse model. For this task, we develop a dictionary of possible eff…
Likelihood ratio map for direct exoplanet detection
Hazan Daglayan, Simon Vary, Faustine Cantalloube +2
Direct imaging of exoplanets is a challenging task due to the small angular distance and high contrast relative to their host star, and the presence of quasi-static noise. We propo…
VIP: Vortex Image Processing package for high-contrast direct imaging
C. A. Gomez Gonzalez, O. Wertz, O. Absil +11
We present the Vortex Image Processing (VIP) library, a python package dedicated to astronomical high-contrast imaging. Our package relies on the extensive python stack of scientif…
Low-rank plus sparse decomposition for exoplanet detection in direct-imaging ADI sequences. The LLSG algorithm
C. A. Gomez Gonzalez, O. Absil, P. -A. Absil +3
Data processing constitutes a critical component of high-contrast exoplanet imaging. Its role is almost as important as the choice of a coronagraph or a wavefront control system, a…
The VORTEX project: first results and perspectives
Olivier Absil, Dimitri Mawet, Christian Delacroix +15
(abridged) Vortex coronagraphs are among the most promising solutions to perform high contrast imaging at small angular separations. They feature a very small inner working angle,…
