Direct Imaging and Astrometric Detection of a Gas Giant Planet Orbiting an Accelerating Star
Thayne Currie, G. Mirek Brandt, Timothy D. Brandt +31
Direct imaging of gas giant exoplanets provides key information on planetary atmospheres and the architectures of planetary systems. However, few planets have been detected in blin…
Astrometric Accelerations as Dynamical Beacons: Discovery and Characterization of HIP 21152 B, the First T-Dwarf Companion in the Hyades
Kyle Franson, Brendan P. Bowler, Mariangela Bonavita +28
Benchmark brown dwarf companions with well-determined ages and model-independent masses are powerful tools to test substellar evolutionary models and probe the formation of giant p…
Three-sided pyramid wavefront sensor. II. Preliminary demonstration on the new CACTI testbed
Lauren Schatz, Johanan Codona, Joseph D. Long +17
The next generation of giant ground and space telescopes will have the light-collecting power to detect and characterize potentially habitable terrestrial exoplanets using high-con…
AO3000 at Subaru: Combining for the first time a NIR WFS using First Light's C-RED ONE and ALPAO's 64x64 DM
Julien Lozi, Kyohoon Ahn, Christophe Clergeon +7
After 16 years of on-sky operation, Subaru Telescope's facility adaptive optics AO188 is getting several major upgrades to become the extreme-AO AO3000 (3000 actuators in the pupil…
Probing Photon Statistics in Adaptive Optics Images with SCExAO/MEC
Sarah Steiger, Timothy D. Brandt, Olivier Guyon +11
We present an experimental study of photon statistics for high-contrast imaging with the Microwave Kinetic Inductance Detector (MKID) Exoplanet Camera (MEC) located behind the Suba…
Controlling petals using fringes: discontinuous wavefront sensing through sparse aperture interferometry at Subaru/SCExAO
Vincent Deo, Sébastien Vievard, Nick Cvetojevic +9
Low wind and petaling effects, caused by the discontinuous apertures of telescopes, are poorly corrected -- if at all -- by commonly used workhorse wavefront sensors (WFSs). Wavefr…
