The Peculiar Periodic YSO WL 4 in Rho Ophiuchus
Peter Plavchan, Alan H. Gee, Karl Stapelfeldt +1
We present the discovery of 130.87 day periodic near-infrared flux variability for the Class II T Tauri star WL 4 (= 2MASS J16271848-2429059, ISO-Oph 128). Our data are from the 2M…
A Spitzer Study of Debris Disks In The Young Nearby Cluster NGC 2232: Icy Planets Are Common Around ~ 1.5--3 Solar-Mass Stars
Thayne Currie, Peter Plavchan, Scott J. Kenyon
We describe Spitzer IRAC and MIPS observations of the nearby 25 Myr-old open cluster NGC 2232. Combining these data with ROSAT All-Sky Survey observations, proper motions, and opti…
Near-Infrared Variability in the 2MASS Calibration Fields: A Search for Planetary Transit Candidates
Peter Plavchan, M. Jura, J. Davy Kirkpatrick +2
The 2MASS photometric calibration observations cover ~6 square degrees on the sky in 35 "calibration fields" each sampled in nominal photometric conditions between 562 and 3692 tim…
Where Are The M Dwarf Disks Older Than 10 Million Years?
Peter Plavchan, M. Jura, S. J. Lipscy
We present 11.7-micron observations of nine late-type dwarfs obtained at the Keck I 10-meter telescope in December 2002 and April 2003. Our targets were selected for their youth or…
Globular Cluster Formation in M82
S. J. Lipscy, P. Plavchan
We present high resolution mid-infrared (mid-IR; 11.7 and 17.65 micron) maps of the central 400 pc region of the starburst galaxy M82. Seven star forming clusters are identified wh…
