JWST's Constraints on the Substellar IMF in NGC 2024
K. L. Luhman
The paper uses JWST NIRCam imaging and NIRSpec spectroscopy to identify brown dwarfs in the young cluster NGC 2024 and assesses whether the substellar initial mass function shows a…
JWST Spectra of Brown Dwarf Candidates in the Orion Nebula Cluster
K. L. Luhman
I present an analysis of archival spectra of 200 sources toward the Orion Nebula Cluster (ONC) that were obtained with the Near-Infrared Spectrograph (NIRSpec) on board the James W…
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…
The Initial Mass Function of Stars and Brown Dwarfs in the Upper Sco Association
K. L. Luhman
I present infrared spectroscopy of 37 brown dwarf candidates in the Upper Sco association, 35 of which are classified as young and cool, making them likely members. This sample inc…
The Membership and Age of the Planet-hosting Young Star IRAS 04125+2902
K. L. Luhman
A transiting planet was recently discovered around a star in the Taurus star-forming region, IRAS 04125+2902, making it one of the youngest known planets. The discovery paper cited…
Extending the ALMA Census of Circumstellar Disks in the Upper Scorpius OB Association
John M. Carpenter, Taran L. Esplin, Kevin L. Luhman +2
We present ALMA Band 7 continuum (340 GHz) and CO J=3-2 observations for an extended sample of disks in the Upper Scorpius OB Association (Upper Sco, age ~ 10 Myr). The targets wer…
