PROTOPLANETARY DISK STRUCTURES IN OPHIUCHUS
We present the results of a high angular resolution (0.''3 {approx} 40 AU) Submillimeter Array survey of the 345 GHz (870 {mu}m) thermal continuum emission from nine of the brightest, and therefore…
The Mass Dependence between Protoplanetary Disks and their Stellar Hosts
We present a substantial extension of the millimeter (mm) wave continuum photometry catalog for circumstellar dust disks in the Taurus star-forming region, based on a new ''snapshot'' {lambda} = 1.3…
Resolved Images of Large Cavities in Protoplanetary Transition Disks
Circumstellar disks are thought to experience a rapid transition phase in their evolution that can have a considerable impact on the formation and early development of planetary systems. We present…
Protoplanetary Disk Structures in Ophiuchus. II. Extension to Fainter Sources
We present new results from a significant extension of our previous high angular resolution (03 40 AU) submillimeter array survey of the 340 GHz (880 μm) thermal continuum emission from dusty…
A Search for Infall Motions toward Nearby Young Stellar Objects
We report observations of 47 candidate protostars in two optically thick lines [H2CO (212-111) and CS (2-1)] and one optically thin line [N2H+ (1-0)] using the IRAM 30 m, SEST 15 m, and Haystack 37 m…
Evidence for a Developing Gap in a 10 Myr Old Protoplanetary Disk
We have developed a physically self-consistent model of the disk around the nearby 10 Myr old star TW Hya that matches the observed spectral energy distribution and 7 mm images of the disk. The model…
Coherence in Dense Cores. II. The Transition to Coherence
After studying how line width depends on spatial scale in low-mass star-forming regions, we propose that dense cores (Myers & Benson 1983) represent an inner scale of a self-similar process that…
Intense star formation within resolved compact regions in a galaxy at z = 2.3
TLDR
Observations of the sub-millimetre galaxy SMMJ2135-0102, which has been gravitationally magnified by a factor of 32 by a massive foreground galaxy cluster lens, find that the luminosity densities of these star-forming regions are comparable to the dense cores of giant molecular clouds in the local Universe, but they are about a hundred times larger and 107 times more luminous.
H I Absorption toward Ultracompact H II Regions: Distances and Galactic Structure
The Very Large Array was used to observe H I absorption against 20 compact and ultracompact H II (UC H II) regions, thereby resolving the kinematic distance ambiguity to these sources. Combining…
A Simple Model of Spectral-Line Profiles from Contracting Clouds
A simple analytic model of radiative transfer in two parts of a contracting cloud matches a wide range of line profiles in candidate infall regions and provides a sensitive estimate of Vin, the…
