Protoplanetary Disks and Their Evolution
Flattened, rotating disks of cool dust and gas extending for tens to hundreds of astronomical units are found around almost all low-mass stars shortly after their birth. These disks generally persistExpand
DETERMINING STRUCTURE IN MOLECULAR CLOUDS
We descibe an automatic, objective routine for analyzing the clumpy structure in a spectral line position-position-velocity data cube. The algorithm works by first contouring the data at a multipleExpand
High-Resolution Submillimeter Constraints on Circumstellar Disk Structure
We present a high spatial resolution submillimeter continuum survey of 24 circumstellar disks in the Taurus-Auriga and Ophiuchus-Scorpius star formation regions using the SMA. In the context of aExpand
THE BOLOCAM GALACTIC PLANE SURVEY: SURVEY DESCRIPTION AND DATA REDUCTION
We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 33'' effective resolution of 170 deg2 of the Galactic Plane visible from the northern hemisphere. The BGPS is one ofExpand
THE GALACTIC DISTRIBUTION OF OB ASSOCIATIONS IN MOLECULAR CLOUDS
Molecular clouds account for half of the mass of the interstellar medium interior to the solar circle and for all current star formation. Using cloud catalogs of two CO surveys of the first quadrant,Expand
A Submillimeter View of Circumstellar Dust Disks in ρ Ophiuchi
We present new multiwavelength submillimeter continuum measurements of the circumstellar dust around 48 young stars in the ρ Ophiuchi dark clouds. Supplemented with previous 1.3 mm observations of anExpand
The Luminosity Function of OB Associations in the Galaxy
OB associations ionize the interstellar medium, producing both localized H II regions and diffuse ionized gas. The supernovae resulting from these associations pressurize and stir the interstellarExpand
ALMA Survey of Lupus Protoplanetary Disks. I. Dust and Gas Masses
We present the first high-resolution sub-millimeter survey of both dust and gas for a large population of protoplanetary disks. Characterizing fundamental properties of protoplanetary disks on aExpand
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, theExpand
A Parametric Modeling Approach to Measuring the Gas Masses of Circumstellar Disks
The disks that surround young stars are mostly composed of molecular gas, which is harder to detect and interpret than the accompanying dust. Disk mass measurements have therefore relied on large andExpand
