The Companions to B and A Stars Snapshot (C-BASS) Survey: I. Discovery of a Young Brown Dwarf Companion to HIP 17453

Marah Brinjikji, Adam J. Smith, Jennifer Patience +26

We report the detection of a new brown dwarf companion to HIP 17453 A, a chemically peculiar A0V star located at a distance of 81 pc. HIP 17453 A was observed with high-resolution…

On the Orbit of the Binary Brown Dwarf Companion GL229 Ba and Bb

William Thompson, Dori Blakely, Jerry W. Xuan +21

The companion GL229B was recently resolved by Xuan et al. (2024) as a tight binary of two brown dwarfs (Ba and Bb) through VLTI-GRAVITY interferometry and VLT-CRIRES+ RV measuremen…

Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645

Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50

The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
