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…
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…
ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets
David Leisawitz, Tom Armstrong, Chad Bender +28
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 - 400 micron wavelength range, a far-IR interferometer will revolutionize our understanding of…
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…
Can We Trust the Dust? Evidence of Dust Segregation in Molecular Clouds
Paolo Padoan, Laurent Cambresy, Mika Juvela +3
Maps of estimated dust column density in molecular clouds are usually assumed to reliably trace the total gas column density structure. In this work we present results showing a cl…
Turbulence driven diffusion in protoplanetary disks - chemical effects in the outer disk
K. Willacy, W. D. Langer, M. Allen +1
The dynamics and chemistry of protostellar disks are likely to be intricately linked, with dynamical processes altering the chemical composition, and chemistry, in turn, controllin…
