89 New Ultracool Dwarf Co-Moving Companions Identified With The Backyard Worlds: Planet 9 Citizen Science Project
Austin Rothermich, Jacqueline K. Faherty, Daniella Bardalez-Gagliuffi +43
We report the identification of 89 new systems containing ultracool dwarf companions to main sequence stars and white dwarfs, using the citizen science project Backyard Worlds: Pla…
The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
The Field Substellar Mass Function Based on the Full-sky 20-pc Census of 525 L, T, and Y Dwarfs
J. Davy Kirkpatrick, Christopher R. Gelino, Jacqueline K. Faherty +49
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of th…
The Ultra-Cool Dwarf Sample III: Seven new multiple systems containing at least one DR2 ultra-cool dwarf
F. Marocco, R. L. Smart, E. E. Mamajek +8
We present ten new ultra-cool dwarfs in seven wide binary systems discovered using DR2 data, identified as part of our Ultra-Cool Dwarf Sample proje…
Hunting for ancient brown dwarfs: the developing field of brown dwarfs in globular clusters
Ilaria Caiazzo, Adam Burgasser, Jon M. Rees +6
The detection of brown dwarfs in globular star clusters will allow us to break the degeneracies in age, mass and composition that affect our current models, and therefore to constr…
A 3 Gyr White Dwarf with Warm Dust Discovered via the Backyard Worlds: Planet 9 Citizen Science Project
John H. Debes, Melina Thevenot, Marc Kuchner +15
Infrared excesses due to dusty disks have been observed orbiting white dwarfs with effective temperatures between 7200 K and 25000 K, suggesting that the rate of tidal disruption o…
