Thirteen New M Dwarf + T Dwarf Pairs Identified with WISE/NEOWISE
Federico Marocco, J. Davy Kirkpatrick, Adam C. Schneider +31
We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using WISE/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 project…
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…
An Atmospheric Retrieval of the Brown Dwarf Gliese 229B
Emily Calamari, Jacqueline K. Faherty, Ben Burningham +6
We present results from an atmospheric retrieval analysis of Gl 229B using the BREWSTER retrieval code. We find the best fit model to be cloud-free, consistent with the T dwarf ret…
Informed systematic method to identify variable mid and late-T dwarfs
Natalia Oliveros-Gómez, Elena Manjavacas, Afra Ashraf +5
The majority of brown dwarfs show some level of photometric or spectro-photometric variability in different wavelength ranges. This variability allow us to trace the 3D atmospheric…
Backyard Worlds: Planet 9 Discovery of an Unusual Low-mass Companion to an M Dwarf at 80 pc
Austin Rothermich, Adam C. Schneider, Jacqueline K. Faherty +7
We present the discovery of CWISE J203546.35-493611.0, a peculiar M8 companion to the M4.5 star APMPM J2036-4936 discovered through the citizen science project Backyard Worlds: Pla…
WISEA J041451.67-585456.7 and WISEA J181006.18-101000.5: The First Extreme T-type Subdwarfs?
Adam C. Schneider, Adam J. Burgasser, Roman Gerasimov +23
We present the discoveries of WISEA J041451.67-585456.7 and WISEA J181006.18-101000.5, two low-temperature (12001400 K), high proper motion T-type subdwarfs. Both objects were d…
Discovery of a Possible Cool White Dwarf Companion from the AllWISE Motion Survey
Sergio B. Fajardo-Acosta, J. Davy Kirkpatrick, Adam C. Schneider +6
We present optical and near-infrared spectroscopy of WISEA J061543.91124726.8, which we rediscovered as a high motion object in the AllWISE survey. The spectra of this object ar…
Hubble Space Telescope Imaging and Spectral Analysis of Two Brown Dwarf Binaries at the L Dwarf/T Dwarf Transition
Adam J. Burgasser, Daniella C. Bardalez Gagliuffi, John E. Gizis
We present a detailed examination of the brown dwarf multiples 2MASS J08503593+1057156 and 2MASS J17281150+3948593, both suspected of harboring components that straddle the L dwarf…
