Young Stellar Objects in the Orion B Cloud [PDF]

, 2015
Wide-field near-infrared imaging surveys offer an excellent opportunity to obtain spatially complete samples of young stars in nearby star-forming regions.

Quantitative Spectroscopic Diagnostics for FU Orionis-type Young Stellar Objects

The Astrophysical Journal
We present near-infrared spectroscopic diagnostics that can be used to identify FU Orionis stars (FUOrs). These young stellar objects are currently in a state of extreme outburst, caused by enhanced mass inflow from their accretion disks.

The evolutionary state of young stellar objects in IRDC G48

, 2007
Spitzer Space Telescope mid-infrared (3–24 m) photometry is processed and analyzed in order to assess the young stellar content of Infrared Dark Cloud G48. It is established from color-color diagram analysis that 40 objects are YSO (Young Stellar Object)

ALMA High-resolution Observation of the HH 46/47 Outflow/Disk/Envelope System

The Astrophysical Journal
We present $0\mathop{.}\limits^{^{\prime\prime} }1$ (∼50 au) resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the HH 46/47 molecular outflow and its envelope–disk system.
