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…

Validation of elemental and isotopic abundances in late-M spectral types with the benchmark HIP 55507 AB system

Jerry W. Xuan, Jason J. Wang, Luke Finnerty +48

M dwarfs are common host stars to exoplanets but often lack atmospheric abundance measurements. Late-M dwarfs are also good analogs to the youngest substellar companions, which sha…

CD-27 11535: Evidence for a Triple System in the Pictoris Moving Group

Andrew D. Thomas, Eric L. Nielsen, Robert J. De Rosa +20

We present new spatially resolved astrometry and photometry of the CD-27 11535 system, a member of the Pictoris moving group consisting of two resolved K-type stars on a …

The Comprehensive Archive of Substellar and Planetary Accretion Rates

S. K. Betti, K. B. Follette, K. Ward-Duong +11

Accretion rates () of young stars show a strong correlation with object mass (); however, extension of the relation into the substellar regime is less certa…
