Discovery of a Young Substellar Companion in Chamaeleon
K. L. Luhman, J. C. Wilson, W. Brandner +6
During an imaging survey of the Chamaeleon I star-forming region with the ACS aboard HST, we have discovered a candidate substellar companion to the young low-mass star CHXR 73 (~2…
Spitzer 24 Micron Observations of Open Cluster IC 2391 and Debris Disk Evolution of FGK Stars
Nick Siegler, James Muzerolle, Erick T. Young +5
We present 24 micron Spitzer/MIPS photometric observations of the ~50 Myr open cluster IC 2391. Thirty-four cluster members ranging in spectral type from B3-M5 were observed in the…
Spitzer/MIPS 24 micron Detection of Photoevaporating Protoplanetary Disks
Z. Balog, G. H. Rieke, K. Y. L. Su +2
We present 24 micron images of three protoplanetary disks being photoevaporated around high mass O type stars. These objects have ``cometary'' structure where the dust pulled away…
Outflows from the high-mass protostars NGC 7538 IRS1/2 observed with bispectrum speckle interferometry -- Signatures of flow precession
S. Kraus, Y. Balega, M. Elitzur +6
NGC 7538 IRS1 is a high-mass (approx. 30 M_sun) protostar with a CO outflow, an associated UCHII region, and a linear methanol maser structure, which might trace a Keplerian-rotati…
24-micron Detections of Disks around Very Low-mass Stars and Brown Dwarfs in IC 348: Grain Growth/Settling and Inner Holes?
James Muzerolle, Lucia Adame, Paola D'Alessio +11
We present observations of six late-type members of the young cluster IC 348 detected at 24 microns with the Multiband Imaging Photometer for Spitzer(MIPS). At least four of the ob…
The Structure and Evolution of Young Stellar Clusters
L. Allen, S. T. Megeath, R. Gutermuth +6
We examine the properties of embedded clusters within 1 kiloparsec using new data from the Spitzer Space Telescope, as well as recent results from 2MASS and other ground-based near…
