The Evolution of Density Structure of Starless and Protostellar Cores
Chao-Ling Hung, Shih-Ping Lai, Chi-Hung Yan
We present a near-infrared extinction study of nine dense cores at evolutionary stages between starless to Class I. Our results show that the density structure of all but one obser…
The Equilibrium Structure of Prolate Magnetized Molecular Cores
Michael J. Cai, Ronald E. Taam
The structure of molecular cloud cores supported by thermal pressure and a poloidal magnetic field is reinvestigated in the magnetohydrostatic and axisymmetric approximation. In ad…

Optical linear polarization in ultra cool dwarfs: A tool to probe dust in the ultra cool dwarf atmospheres
R. Tata, E. L. Martin, S. Sengupta +3
Aims.Recent studies have detected linear polarization in L dwarfs in the optical I band. Theoretical models have been developed to explain this polarization. These models predict h…
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite I. The observational data
A. O. H. Olofsson, C. M. Persson, N. Koning +14
Spectral line surveys are useful since they allow identification of new molecules and new lines in uniformly calibrated data sets. Nonetheless, large portions of the sub-millimetre…
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite II. Data analysis
C. M. Persson, A. O. H. Olofsson, N. Koning +14
We investigate the physical and chemical conditions in a typical star forming region, including an unbiased search for new molecules in a spectral region previously unobserved. Due…
Thermal Response of A Solar-like Atmosphere to An Electron Beam from A Hot Jupiter: A Numerical Experiment
Pin-Gao Gu, Takeru K. Suzuki
We investigate the thermal response of the atmosphere of a solar-type star to an electron beam injected from a hot Jupiter by performing a 1-dimensional magnetohydrodynamic numeric…
Magnetic Field Topology in Low-Mass Stars: Spectropolarimetric Observations of M Dwarfs
N. Phan-Bao, J. Lim, J. -F. Donati +2
(ABRIDGED) We report here our mapping of the magnetic field topology of the M4 dwarf G 164-31 (or Gl 490B), which is expected to be fully convective, based on time series data coll…
Stringent Limits on the Polarized Submillimeter Emission from Protoplanetary Disks

We present arcsecond-resolution Submillimeter Array (SMA) polarimetric observations of the 880 um continuum emission from the protoplanetary disks around two nearby stars, HD 16329…
Evolutionary Status of Brightest and Youngest Source in the Orion Molecular Cloud-3 Region
Satoko Takahashi, Paul T. P. Ho, Ya-Wen Tang +2
The brightest continuum source in the Orion Molecular Cloud-3 region (OMC-3), MMS 6, was observed with the Very Large Array (VLA), the Nobeyama Millimeter Array (NMA), and the Subm…
Emission from a Young Protostellar Object I. Signatures of Young Embedded Outflows
M. Yamada, M. N. Machida, S. Inutsuka +1
We examine emission from a young protostellar object (YPO) with three-dimensional ideal MHD simulations and three-dimensional non-local thermodynamic equilibrium (non-LTE) line tra…
