Silicate Precursor Silane detected in Cold Low-Metallicity Brown Dwarf
Jacqueline K. Faherty, Aaron M. Meisner, Ben Burningham +28
Within 20 pc of the Sun there are currently 29 known cold brown dwarfs, sources with measured distances and an estimated effective temperature between that of Jupiter (170K) and ~5…
Benchmark brown dwarfs -- I. A blue M2 + T5 wide binary and a probable young [M4 + M4] + [T7 + T8] hierarchical quadruple
Z. H. Zhang, F. Navarete, M. C. Galvez-Ortiz +13
Benchmark brown dwarfs in wide binary systems are crucial for characterizing substellar objects and calibrating atmospheric and evolutionary models. However, brown dwarf benchmarks…
Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. MartÃn +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…
Detection of Methane in the Closest Extreme Metal-poor T Dwarf WISEA J181006.18-101000.5
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. MartÃn +7
WISEA J181006.18-101000.5 (WISE1810) is the nearest metal-poor ultracool dwarf to the Sun. It has a low effective temperature and has been classified as extreme early-T subdwarf. H…
