Alignment Between Flattened Protostellar Infall Envelopes and Ambient Magnetic Fields

Nicholas L. Chapman, Jacqueline A. Davidson, Paul F. Goldsmith +10

We present 350 micron polarization observations of four low-mass cores containing Class 0 protostars: L483, L1157, L1448-IRS2, and Serp-FIR1. This is the second paper in a larger s…

The molecular emissions and the infall motion in the high-mass young stellar object G8.68-0.37

Zhiyuan Ren, Yuefang Wu, Ming Zhu +5

We present a multi-wavelength observational study towards the high-mass young stellar object G8.68-0.37. A single massive gas-and-dust core is observed in the (sub)millimeter conti…

Discovery of Hydrogen Fluoride in the Cloverleaf Quasar at z = 2.56

R. R. Monje, T. G. Phillips, R. Peng +3

We report the first detection of hydrogen fluoride (HF) toward a high redshift quasar. Using the Caltech Submillimeter Observatory (CSO) we detect the HF J = 1 - 0 transition in ab…

Rotation State of Comet 103P/Hartley 2 from Radio Spectroscopy at 1 mm

Michal Drahus, David Jewitt, Aurelie Guilbert-Lepoutre +6

The nuclei of active comets emit molecules anisotropically from discrete vents. As the nucleus rotates, we expect to observe periodic variability in the molecular emission line pro…

A Comprehensive Survey of Hydrogen Chloride in the Galaxy

Ruisheng Peng, Hiroshige Yoshida, Richard A. Chamberlin +3

We report new observations of the fundamental transition of HCl (at 625.918GHz) toward a sample of 25 galactic star-forming regions, molecular clouds, and evolved stars, ca…

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…
