Paper time: Redder than Red- The reddest known free-floating L/T dwarf (A. Schneider et al). We suggest β Pic membership, young age and mass <13 Jupiter masses. We also report possible IR variability based on WISE photometry. arxiv.org/abs/2301.02322 @caltechipac @backyardworlds

Go, Austin! #aas241
Replying to @jfaherty
Graduate student Austin Rothermich presented on his upcoming paper characterizing a big new catalog of benchmark brown dwarfs. Austin started as a citizen scientist with @backyardworlds and this is the culmination of the work he started as an undergrad with me!

It's been a busy #aas241!
Replying to @jfaherty
Another @backyardworlds presentation was given by undergraduate Hunter Brooks on discovering 124 new brown dwarf candidates with a machine learning technique (which happened to be developed by the amazing Dan Caselden)
