HWO's Tier 1 Contrast Stability Technology Gap presents a key challenge for technology development in the coming years, requiring to a >100x more stable system than JWST. WaveDrive…
HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen
Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51
We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…
Developments on LLNL's high contrast testbed and Lick/ShaneAO
Benjamin L. Gerard, Dominic F. Sanchez, Aditya R. Sengupta +15
LLNL has recently setup a High Contrast Testbed (HCT) for AO and exoplanet imaging technology development. We present the various HCT technologies currently under development, incl…
GPI 2.0: Exploring The Impact of Different Readout Modes on the Wavefront Sensor's EMCCD
Clarissa R. Do Ã, Saavidra Perera, Jérôme Maire +26
The Gemini Planet Imager (GPI) is a high contrast imaging instrument that aims to detect and characterize extrasolar planets. GPI is being upgraded to GPI 2.0, with several subsyst…
