Dichotomy in the Dynamical Status of Massive Cores in Orion
T. velusamy, R. Peng, D. Li +2
To study the evolution of high mass cores, we have searched for evidence of collapse motions in a large sample of starless cores in the Orion molecular cloud. We used the Caltech S…
Spitzer Observations of Bok Globule B335: Isolated Star Formation Efficiency and Cloud Structure
Amelia M. Stutz, Mark Rubin, Michael W. Werner +8
We present infrared and millimeter observations of Barnard 335, the prototypical isolated Bok globule with an embedded protostar. Using Spitzer data we measure the source luminosit…
Highly Collimated Jets and Wide-Angle Outflows in HH46/47: New Evidence from Spitzer IR Images
T. Velusamy, W. D. Langer, K. A. Marsh
We present new details of the structure and morphology of the jets and outflows in HH46/47 as seen in Spitzer infrared images from IRAC and MIPS, reprocessed using the ``HiRes'' de…
New Debris Disks Around Nearby Main Sequence Stars: Impact on The Direct Detection of Planets
C. Beichman, G. Bryden, K. Stapelfeldt
Using the MIPS instrument on the Spitzer telescope, we have searched for infrared excesses around a sample of 82 stars, mostly F, G, and K main-sequence field stars, along with a s…
Massive Quiescent Cores in Orion. -- II. Core Mass Function
D. Li, T. Velusamy, P. F. Goldsmith +1
We have surveyed submillimeter continuum emission from relatively quiescent regions in the Orion molecular cloud to determine how the core mass function in a high mass star forming…
Point Process Algorithm: A New Bayesian Approach for Planet Signal Extraction with the Terrestrial Planet Finder
K. A. Marsh, T. Velusamy, B. Ware
The capability of the Terrestrial Planet Finder Interferometer (TPF-I) for planetary signal extraction, including both detection and spectral characterization, can be optimized by…
