Technology and Science Advancing Observations with Roman Coronagraph Informed by Ground-Based High-Contrast Imaging
Mona El Morsy, Thayne Currie, Brianna Lacy +10
The Roman Coronagraph technology demonstration focuses on achieving 10 contrasts within the instrument's dark hole and our ability to detect and characterize properties…
A Roman Coronagraph Spectroscopic Mode Demonstration
Thayne Currie, Brianna Lacy, Yiting Li +5
We propose 730 nm high-contrast spectroscopic observations of selected self-luminous directly-imaged planets as a key test of the Roman Coronagraph's planet characterization capabi…
Decisively Demonstrating Roman CGI's TTR5 Requirement by Reimaging a Newly-Discovered Brown Dwarf Orbiting a Bright Accelerating Star
Thayne Currie, Mona El Morsy, Brianna Lacy +3
We propose Roman Coronagraph project HLC/575 nm observations of a newly-discovered brown dwarf (HIP 71618 B) from the Subaru/OASIS survey of young accelerating stars, which is supp…
The HIP 54515 b Superjovian Planet as an Early, Critical Look at the Roman Coronagraph's Performance in the Faint Target Star, Small IWA Limit
Thayne Currie, Yiting Li, Brianna Lacy +4
The Roman Coronagraph's capabilities in the faint star, small IWA limit has enormous scientific (programmatic) impacts. Testing its performance in this limit provides a first look…
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-…
