An Imaging Search for Post-Main-Sequence Planets of Sirius B
Miles Lucas, Michael Bottom, Garreth Ruane +1
We present deep imaging of Sirius B, the closest and brightest white dwarf, to constrain post-main-sequence planetary evolution in the Sirius system. We use Keck/NIRC2 in L'-band (…
High contrast imaging at the photon noise limit with self-calibrating WFS/C systems
Olivier Guyon, Barnaby Norris, Marc-Antoine Martinod +20
High contrast imaging (HCI) systems rely on active wavefront control (WFC) to deliver deep raw contrast in the focal plane, and on calibration techniques to further enhance contras…
SCExAO, a testbed for developing high-contrast imaging technologies for ELTs
Kyohoon Ahn, Olivier Guyon, Julien Lozi +21
To directly detect exoplanets and protoplanetary disks, the development of high accuracy wavefront sensing and control (WFS&C) technologies is essential, especially for ground-base…
Constraining the Orbit and Mass of epsilon Eridani b with Radial Velocities, Hipparcos IAD-Gaia DR2 Astrometry, and Multi-epoch Vortex Coronagraphy Upper Limits
Jorge Llop-Sayson, Jason J. Wang, Jean-Baptiste Ruffio +30
~Eridani is a young planetary system hosting a complex multi-belt debris disk and a confirmed Jupiter-like planet orbiting at 3.48 AU from its host star. Its age and architectur…
"Fast" and Furious focal-plane wavefront sensing at W. M. Keck Observatory
Steven P. Bos, Michael Bottom, Sam Ragland +3
High quality, repeatable point-spread functions are important for science cases like direct exoplanet imaging, high-precision astrometry, and high-resolution spectroscopy of exopla…
Exoplanet Imaging Data Challenge: benchmarking the various image processing methods for exoplanet detection
F. Cantalloube, C. Gomez-Gonzalez, O. Absil +23
The Exoplanet Imaging Data Challenge is a community-wide effort meant to offer a platform for a fair and common comparison of image processing methods designed for exoplanet direct…
