A New Spectral Class of Brown Dwarfs at the Bottom of the IMF in IC 348
K. L. Luhman, C. Alves de Oliveira
In a previous study, we used JWST to identify three new brown dwarfs in the center of a nearby star-forming cluster, IC 348. The faintest object had an estimated mass of 3-4 $M_{\r…

Medium Resolution 0.97-5.3 micron spectra of Very Young Benchmark Brown Dwarfs with NIRSpec onboard the James Webb Space Telescope
Elena Manjavacas, Pascal Tremblin, Stephan Birkmann +7
Spectra of young benchmark brown dwarfs with well-known ages are vital to characterize other brown dwarfs, for which ages are in general not known. These spectra are also crucial t…

JWST/NIRSpec Observations of the Coldest Known Brown Dwarf
K. L. Luhman, P. Tremblin, C. Alves de Oliveira +6
We present 1-5um spectroscopy of the coldest known brown dwarf, WISE J085510.83-071442.5 (WISE 0855), performed with the Near-Infrared Spectrograph (NIRSpec) on board the James Web…
