Discovery of a Planetary-Mass Brown Dwarf with a Circumstellar Disk
K. L. Luhman, Lucia Adame, Paola D'Alessio +4
Using the Hubble Space Telescope, the 4 m Blanco telescope at the Cerro Tololo Inter-American Observatory, and the Spitzer Space Telescope, we have performed deep imaging from 0.8…
Identifying Primordial Substructure in NGC 2264
Paula S. Teixeira, Charles J. Lada, Erick T. Young +8
We present new Spitzer Space Telescope observations of the young cluster NGC2264. Observations at 24 micron with the Multiband Imaging Photometer has enabled us to identify the mos…
Effects of Dust Growth and Settling in T Tauri Disks
Paola D'Alessio, Nuria Calvet, Lee Hartmann +2
We present self-consistent disk models for T Tauri stars which include a parameterized treatment of dust settling and grain growth, building on techniques developed in a series of…
Spitzer/IRAC Photometry of the Eta Chameleontis Association
S. T. Megeath, L. Hartmann, K. L. Luhman +1
We present IRAC 3.6, 4.5, 5.8 and 8 micron photometry for the 17 A, K and M type members of the Eta Chameleontis association. These data show infrared excesses toward six of the 15…
The Disk Fractions of Brown Dwarfs in IC 348 and Chamaeleon I
K. L. Luhman, C. J. Lada, L. Hartmann +7
Using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope, we have obtained mid-infrared photometry for 25 and 18 low-mass members of the IC 348 and Chamaeleon I st…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
