Exploring the Extremes: Characterizing a New Population of Old and Cold Brown Dwarfs
A. M. Meisner, S. K. Leggett, S. E. Logsdon +3
Mapping out the populations of thick disk and halo brown dwarfs is important for understanding the metallicity dependence of low-temperature atmospheres and the substellar mass fun…
Detection of p-mode Oscillations in HD 35833 with NEID and TESS
Arvind F. Gupta, Jacob K. Luhn, Jason T. Wright +15
We report the results of observations of p-mode oscillations in the G0 subgiant star HD 35833 in both radial velocities and photometry with NEID and TESS, respectively. We achieve…
Measuring and Replicating the 1-20 um Energy Distributions of the Coldest Brown Dwarfs: Rotating, Turbulent and Non-Adiabatic Atmospheres
S. K. Leggett, Pascal Tremblin, Mark W. Phillips +7
Cold, low-mass, field brown dwarfs are important for constraining the terminus of the stellar mass function, and also for optimizing atmospheric studies of exoplanets. In 2020 new…
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…
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…
Estimating the Ultraviolet Emission of M dwarfs with Exoplanets from Ca II and H
Katherine Melbourne, Allison Youngblood, Kevin France +29
M dwarf stars are excellent candidates around which to search for exoplanets, including temperate, Earth-sized planets. To evaluate the photochemistry of the planetary atmosphere,…
