Kinematic and Spatial Substructure in NGC 2264
John J. Tobin, Lee Hartmann, Gabor Furesz +2
We present an expanded kinematic study of the young cluster NGC 2264 based upon optical radial velocities measured using multi-fiber echelle spectroscopy at the 6.5 meter MMT and M…
Evidence for Environmental Dependence of the Upper Stellar Initial Mass Function in Orion A
Wen-hsin Hsu, Lee Hartmann, Lori Allen +4
We extend our previous study of the stellar population of L1641, the lower-density star-forming region of the Orion A cloud south of the dense Orion Nebula Cluster (ONC), with the…
The Low-mass Stellar Population in L1641: Evidence for Environmental Dependence of the Stellar Initial Mass Function
Wen-Hsin Hsu, Lee Hartmann, Lori Allen +5
We present results from an optical photometric and spectroscopic survey of the young stellar population in L1641, the low-density star-forming region of the Orion A cloud south of…
Physical Properties of Complex C Halo Clouds
W. -H. Hsu, M. E. Putman, F. Heitsch +3
Observations from the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) Survey of the tail of Complex C are presented and the halo clouds associated with this complex cataloged. The…
Competitive Accretion in Sheet Geometry and the Stellar IMF
Wen-hsin Hsu, Lee Hartmann, Fabian Heitsch +1
We report a set of numerical experiments aimed at addressing the applicability of competitive accretion to explain the high-mass end of the stellar initial mass function in a sheet…
The Disruption and Fueling of M33
M. E. Putman, J. E. G. Peek, A. Muratov +7
The disruption of the M33 galaxy is evident from its extended gaseous structure. We present new data from the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) Survey that show the…
