Improved infrared photometry and a preliminary parallax measurement for the extremely cold brown dwarf CWISEP J144606.62231717.8
Federico Marocco, J. Davy Kirkpatrick, Aaron M. Meisner +6
We present follow-up observations at 3.6m (ch1) and 4.5m (ch2) of CWISEP J144606.62231717.8, one of the coldest known brown dwarfs in the solar neighborhood. Thi…
Expanding the Y Dwarf Census with Spitzer Follow-up of the Coldest CatWISE Solar Neighborhood Discoveries
Aaron M. Meisner, Dan Caselden, J. Davy Kirkpatrick +11
We present Spitzer 3.6m and 4.5m follow-up of 170 candidate extremely cool brown dwarfs newly discovered via the combination of WISE and NEOWISE imaging at 35m. CatWISE…

Bryce T. Bolin, Carey M. Lisse, Mansi M. Kasliwal +52
We present visible and near-infrared photometric and spectroscopic observations of interstellar object 2I/Borisov taken from 2019 September 10 to 2019 November 29 using the GROWTH,…
The CatWISE Preliminary Catalog: Motions from and Data
Peter R. M. Eisenhardt, Federico Marocco, John W. Fowler +19
CatWISE is a program to catalog sources selected from combined and all-sky survey data at 3.4 and 4.6 m (W1 and W2). The CatWISE Preliminary Catalog…
CWISEP J193518.59154620.3: An Extremely Cold Brown Dwarf in the Solar Neighborhood Discovered with CatWISE
Federico Marocco, Dan Caselden, Aaron M. Meisner +17
We present the discovery of an extremely cold, nearby brown dwarf in the solar neighborhood, found in the CatWISE catalog (Eisenhardt et al., in prep.). Photometric follow-up with…
Substellar Multiplicity Throughout the Ages
Daniella Bardalez Gagliuffi, Kimberly Ward-Duong, Jacqueline Faherty +11
Substellar multiplicity is a key outcome of the formation process. The biggest challenge for the next decade will be to distinguish between the formation history, environmental con…
