SCExAO/CHARIS and Gaia Direct Imaging and Astrometric Discovery of a Superjovian Planet 3--4 lambda/D from the Accelerating Star HIP 54515
Thayne Currie, Yiting Li, Mona El Morsy +28
We present the discovery of a superjovian planet around the young A5 star HIP 54515, detected using precision astrometry from the Hipparcos Gaia Catalogue of Accelerations and high…
OASIS Survey Direct Imaging and Astrometric Discovery of HIP 71618 B: A Substellar Companion Suitable for the Roman Coronagraph Technology Demonstration
Mona El Morsy, Thayne Currie, Brianna Lacy +27
We present the OASIS survey program discovery of a substellar companion orbiting the young A1V star HIP 71618, detected using precision astrometry from Gaia and Hipparcos and high-…
Roman coronagraph simulations of exozodi observations in the presence of wavefront errors
Jorge Llop-Sayson, Vanessa P. Bailey, Justin Hom +6
The Coronagraph Instrument on board of the Nancy Grace Roman Space Telescope will demonstrate key technologies that will prepare the ground for the Habitable Worlds Observatory. Th…
CoronaGraph Instrument Reference stars for Exoplanets (CorGI-REx) I. Preliminary Vetting and Implications for the Roman Coronagraph and Habitable Worlds Observatory
Justin Hom, Schuyler G. Wolff, Catherine A. Clark +28
The upcoming Roman Coronagraph will be the first high-contrast instrument in space capable of high-order wavefront sensing and control technologies, a critical technology demonstra…
Are We There Yet? Challenges in Quantifying the Frequency of Earth Analogs in the Habitable Zone
Rachel B. Fernandes, Samson Johnson, Galen J. Bergsten +43
Searching for life elsewhere in the universe is one of the most highly prioritized pursuits in astronomy today. However, the ability to observe evidence of Earth-like life through…
Flight masks of the Roman Space Telescope Coronagraph Instrument
A. J. Eldorado Riggs, Vanessa P. Bailey, Dwight Moody +25
Over the past two decades, thousands of confirmed exoplanets have been detected. The next major challenge is to characterize these other worlds and their stellar systems. Much info…
GRIP: a generic data reduction package for nulling interferometry
Marc-Antoine Martinod, Denis Defrere, Romain Laugier +4
Nulling interferometry is a powerful observing technique to study exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes. With re…
Exozodiacal dust as a limitation to exoplanet imaging and spectroscopy
Miles H. Currie, John Debes, Yasuhiro Hasegawa +7
In addition to planets and other small bodies, stellar systems will likely also host exozodiacal dust, or exozodi. This warm dust primarily resides in or near the habitable zone of…
