Discovery of a Low-Mass Companion to the Accelerating Star HIP 53005 with Strongly Conflicting Mass Estimates

Taichi Uyama, Thayne Currie, Jerry W. Xuan +22

We present the discovery of a low-mass companion located at 0\farcs{}85 () from the early-type 1.2 Gyr-old star HIP 53005 using direct imagin…

The Physics of Mass Transfer in Substellar and Low-Mass Binaries

Samuel Whitebook, Jim Fuller, Kevin Burdge +3

Several dozen binary ultracool and brown dwarf systems have been identified to date. These systems represent valuable probes of star and planet formation at the lowest mass scales.…

A Mass Transferring Brown Dwarf Binary on a 57 Minute Orbit

Samuel Whitebook, Antonio C. Rodriguez, Kevin Burdge +9

Mass transfer in stellar binaries has been well studied in most stellar mass ranges, with the notable exception of ultracool stars and substellar brown dwarfs. We report the discov…

Direct Imaging Explorations for Companions from the Subaru/IRD Strategic Program II; Discovery of a Brown-dwarf Companion around a Nearby mid-M~dwarf LSPM~J1446+4633

Taichi Uyama, Masayuki Kuzuhara, Charles Beichman +35

We report the discovery of a new directly-imaged brown dwarf companion with Keck/NIRC2+pyWFS around a nearby mid-type M~dwarf LSPM~J1446+4633 (hereafter J1446). The -band contr…

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…

Atmospheric abundances and bulk properties of the binary brown dwarf Gliese 229 Bab from JWST/MIRI spectroscopy

Jerry W. Xuan, Marshall D. Perrin, Dimitri Mawet +8

We present JWST/MIRI low-resolution spectroscopy (m) of the first known substellar companion, Gliese 229 Bab, which was recently resolved into a tight binary brown dwarf…
