Disk Evolution in W5: Intermediate Mass Stars at 2-5 Myr
Xavier P. Koenig, Lori E. Allen
We present the results of a survey of young intermediate mass stars (age ~5 Myr, 1.5 15 ) in the W5 massive star forming region. We use combined op…
The Spitzer c2d Survey of Weak-Line T Tauri Stars. III. The Transition from Primordial Disks to Debris Disks
Zahed Wahhaj, Lucas Cieza, Karl R. Stapelfeldt +15
We present 3.6 to 70 μm Spitzer photometry of 154 weak-line T Tauri stars (WTTS) in the Chamaeleon, Lupus, Ophiuchus and Taurus star formation regions, all of which are within 200…
The Star Formation Rate and Gas Surface Density Relation in the Milky Way: Implications for Extragalactic Studies
Amanda Heiderman, Neal J. Evans, Lori E. Allen +2
We investigate the relation between star formation rate (SFR) and gas surface densities in Galactic star forming regions using a sample of YSOs and massive clumps. Our YSO sample c…
A Spitzer View of Star Formation in the Cygnus X North Complex
I. M. Beerer, X. P. Koenig, J. L. Hora +17
We present new images and photometry of the massive star forming complex Cygnus X obtained with IRAC and MIPS on the Spitzer Space Telescope. A combination of IRAC, MIPS, UKIDSS, a…
The Properties of X-ray Luminous Young Stellar Objects in the NGC 1333 and Serpens Embedded Clusters
E. Winston, S. T. Megeath, S. Wolk +9
We present Chandra X-ray data of the NGC 1333 embedded cluster, combining these data with existing Chandra data, Sptizer photometry and ground based spectroscopy of both the NGC 13…
Circumstellar Structure around Evolved Stars in the Cygnus-X Star Formation Region
Kathleen E. Kraemer, Joseph L. Hora, Michael P. Egan +15
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the C…
