A Wide Planetary Mass Companion Discovered Through the Citizen Science Project Backyard Worlds: Planet 9
Jacqueline K. Faherty, Jonathan Gagne, Mark Popinchalk +24
Through the Backyard Worlds: Planet 9 citizen science project we discovered a late-type L dwarf co-moving with the young K0 star BD+60 1417 at a projected separation of 37" or 1662…
Beyond the Local Volume. I. Surface Densities of Ultracool Dwarfs in Deep HST/WFC3 Parallel Fields
Christian Aganze, Adam J Burgasser, Mathew Malkan +6
Ultracool dwarf stars and brown dwarfs provide a unique probe of large-scale Galactic structure and evolution; however, until recently spectroscopic samples of sufficient size, dep…
Discovery of a low-mass comoving system using NOIRLab Source Catalog DR2
Frank Kiwy, Jacqueline Faherty, Aaron Meisner +6
We present the discovery of a low-mass comoving system found by means of the NOIRLab Source Catalog (NSC) DR2. The system consists of the high proper-motion star LEHPM 5005 and an…
Ross 19B: An Extremely Cold Companion Discovered via the Backyard Worlds: Planet 9 Citizen Science Project
Adam C. Schneider, Aaron M. Meisner, Jonathan Gagne +27
Through the Backyard Worlds: Planet 9 citizen science project, we have identified a wide-separation (10', 9900 au projected) substellar companion to the nearby (1…
The Brown Dwarf Kinematics Project (BDKP). V. Radial and Rotational Velocities of T Dwarfs from Keck/NIRSPEC High-Resolution Spectroscopy
Chih-Chun Hsu, Adam J. Burgasser, Christopher A. Theissen +7
We report multi-epoch radial velocities, rotational velocities, and atmospheric parameters for 37 T-type brown dwarfs observed with Keck/NIRSPEC. Using a Markov Chain Monte Carlo f…
New Candidate Extreme T Subdwarfs from the Backyard Worlds: Planet 9 Citizen Science Project
Aaron M. Meisner, Adam C. Schneider, Adam J. Burgasser +29
Schneider et al. (2020) presented the discovery of WISEA J041451.67-585456.7 and WISEA J181006.18-101000.5, which appear to be the first examples of extreme T-type subdwarfs (esdTs…
An Early-Time Optical and Ultraviolet Excess in the type-Ic SN 2020oi
Alexander Gagliano, Luca Izzo, Charles D. Kilpatrick +30
We present photometric and spectroscopic observations of Supernova 2020oi (SN 2020oi), a nearby (17 Mpc) type-Ic supernova (SN Ic) within the grand-design spiral M100. We und…
