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…
Rotation and Abundances of the Benchmark Brown Dwarf HD 33632 Ab from Keck/KPIC High-resolution Spectroscopy
Chih-Chun Hsu, Jason J. Wang, Jerry W. Xuan +24
We present the projected rotational velocity and molecular abundances for HD 33632 Ab obtained via Keck Planet Imager and Characterizer high-resolution spectroscopy. HD 33632 Ab is…
Orbital and Atmospheric Characterization of the 1RXS J034231.8+121622 System Using High-Resolution Spectroscopy Confirms That The Companion is a Low-Mass Star
Clarissa R. Do Ó, Ben Sappey, Quinn M. Konopacky +33
The 1RXS J034231.8+121622 system consists of an M dwarf primary and a directly imaged low-mass stellar companion. We use high resolution spectroscopic data from Keck/KPIC to estima…
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…
From Dust to Nanodust: Resolving Circumstellar Dust from the Colliding-Wind Binary Wolf-Rayet (WR) 140
Ryan M. Lau, Jason Wang, Matthew J. Hankins +17
Wolf-Rayet (WR) 140 is the archetypal periodic dust-forming colliding-wind binary that hosts a carbon-rich WR (WC) star and an O-star companion with an orbital period of 7.93 years…
