A Census of the Young Cluster IC 348
We present a new census of the stellar and substellar members of the young cluster IC 348. We have obtained images at I and Z for a 42' × 28' field encompassing the cluster and have combined theseExpand

Spitzer Observations of IC 348: The Disk Population at 2-3 Million Years
We present near- and mid-infrared photometry obtained with the Spitzer Space Telescope of ~300 known members of the IC?348 cluster. We merge this photometry with existing ground-based optical andExpand

Low-Mass Star Formation and the Initial Mass Function in the ρ Ophiuchi Cloud Core
We have obtained moderate-resolution (R = 800-1200) K-band spectra for ~100 stars within and surrounding the cloud core of ρ Oph. We have measured spectral types and continuum veilings and haveExpand

The Stellar Population of the Chamaeleon I Star-Forming Region
I present a new census of the stellar population in the Chamaeleon I star-forming region. Using optical and near-IR photometry and follow-up spectroscopy, I have discovered 50 new members ofExpand

IRAC OBSERVATIONS OF TAURUS PRE-MAIN-SEQUENCE STARS
We present infrared photometry obtained with the IRAC camera on the Spitzer Space Telescope of a sample of 82 pre-main-sequence stars and brown dwarfs in the Taurus star-forming region. We find aExpand

The Initial Mass Function in the Taurus Star-forming Region*
By combining a deep optical imaging (I; z 0 ) survey of 8 deg 2 in the Taurus star-forming region with data from the Two-Micron All-Sky Survey (2MASS) and follow-up spectroscopy, we have performed aExpand

The Disk Population of the Taurus Star-Forming Region
We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0, and 24??m that were obtained during the cryogenic mission of the Spitzer Space Telescope (46 deg2) and haveExpand

Spitzer IRAC Photometry of M, L, and T Dwarfs
We present the results of a program to acquire photometry for 86 late M, L, and T dwarfs using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We examine the behavior of these coolExpand

DISCOVERY OF A ∼250 K BROWN DWARF AT 2 pc FROM THE SUN*
Through a previous analysis of multi-epoch astrometry from the Wide-field Infrared Survey Explorer (WISE), I identified WISE J085510.83–071442.5 as a new high proper motion object. By combiningExpand

Young Low-Mass Stars and Brown Dwarfs in IC 348
I present new results from a continuing program to identify and characterize the low-mass stellar and substellar populations in the young cluster IC 348 (0.5-10 Myr). Optical spectroscopy hasExpand
