A low-mass companion desert among intermediate-mass visual binaries: The scaled-up counterpart to the brown dwarf desert
G. Duchene, J. T. Oon, R. J. De Rosa +8
We present a high-contrast imaging survey of intermediate-mass (1.75--4.5 ) stars to search for the most extreme stellar binaries, i.e., for the lowest mass stellar compan…
The Giant Accreting Protoplanet Survey (GAPlanetS) -- Results from a Six Year Campaign to Image Accreting Protoplanets
Katherine B. Follette, Laird M. Close, Jared R. Males +20
Accreting protoplanets represent a window into planet formation processes. We report Hα differential imaging results from the deepest and most comprehensive accreting protoplanet s…
Deep orbital search for additional planets in the HR 8799 system
William Thompson, Christian Marois, Clarissa R. Do Ó +6
The HR 8799 system hosts four massive planets orbiting 15 and 80 AU. Studies of the system's orbital stability and its outer debris disk open the possibility of additional planets,…
Stellar Flyby Analysis for Spiral Arm Hosts with Gaia DR3
Linling Shuai, Bin B. Ren, Ruobing Dong +5
Scattered light imaging studies have detected nearly two dozen spiral arm systems in circumstellar disks, yet the formation mechanisms for most of them are still under debate. Alth…
Atmospheric Monitoring and Precise Spectroscopy of the HR 8799 Planets with SCExAO/CHARIS
Jason J. Wang, Peter Gao, Jeffrey Chilcote +10
The atmospheres of gas giant planets are thought to be inhomogeneous due to weather and patchy clouds. We present two full nights of coronagraphic observations of the HR 8799 plane…
Learning about AGB stars by studying the stars polluted by their outflows
Ana Escorza, Robert J. De Rosa
A rich zoo of peculiar objects forms when Asymptotic Giant Branch (AGB) stars, undergo interactions in a binary system. For example, Barium (Ba) stars are main-sequence and red-gia…
