IN-SYNC II: Virial Stars from Sub-Virial Cores -- The Velocity Dispersion of Embedded Pre-Main-Sequence Stars in NGC 1333
Jonathan B. Foster, Michiel Cottaar, Kevin R. Covey +14
The initial velocity dispersion of newborn stars is a major unconstrained aspect of star formation theory. Using near-infrared spectra obtained with the APOGEE spectrograph, we sho…
Young Stellar Object Variability (YSOVAR): Long Timescale Variations in the Mid-Infrared
L. M. Rebull, A. M. Cody, K. R. Covey +32
The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the first extensive mid-infrared (3.6 & 4.5 um) time-series photometry of the Orion…
YSOVAR: Mid-IR variability in the star forming region Lynds 1688
H. M. Günther, A. M. Cody, K. R. Covey +14
The emission from young stellar objects (YSOs) in the mid-IR is dominated by the inner rim of their circumstellar disks. We present an IR-monitoring survey of about 800 objects in…
An X-ray and Infrared Survey of the Lynds 1228 Cloud Core
Stephen Skinner, Luisa Rebull, Manuel Guedel
The nearby Lynds 1228 (L1228) dark cloud at a distance of ~200 pc is known to harbor several young stars including the driving sources of the giant HH 199 and HH 200 Herbig-Haro ou…
CSI 2264: Characterizing Accretion-Burst Dominated Light Curves for Young Stars in NGC 2264
John Stauffer, Ann Marie Cody, Annie Baglin +25
Based on more than four weeks of continuous high cadence photometric monitoring of several hundred members of the young cluster NGC 2264 with two space telescopes, NASA's Spitzer a…
CSI 2264: Simultaneous optical and infrared light curves of young disk-bearing stars in NGC 2264 with CoRoT and Spitzer-- evidence for multiple origins of variability
Ann Marie Cody, John Stauffer, Annie Baglin +42
We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30-day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16…
