A Herschel Search For Cold Dust in Brown Dwarf Disks: First Results
Paul M. Harvey, Thomas Henning, Francois Menard +7
We report initial results from a {\it Herschel} program to search for far-infrared emission from cold dust around a statistically significant sample of young brown dwarfs. The firs…
Herschel Observations of the T Cha Transition Disk: Constraining the Outer Disk Properties
Lucas A. Cieza, Johan Olofsson, Paul M. Harvey +7
T Cha is a nearby (d = 100 pc) transition disk known to have an optically thin gap separating optically thick inner and outer disk components. Huelamo et al. (2011) recently report…
The Bolocam Galactic Plane Survey. VII. Characterizing the Properties of Massive Star-Forming Regions
Miranda K. Dunham, Erik Rosolowsky, Neal J. Evans +2
We present the results of a GBT survey of NH3(1,1), (2,2), (3,3) lines towards 631 Bolocam Galactic Plane Survey (BGPS) sources at a range of Galactic longitudes in the inner Galax…
Ices in starless and starforming cores
Karin I. Oberg, A. C. Adwin Boogert, Klaus M. Pontoppidan +5
Icy grain mantles are commonly observed through infrared spectroscopy toward dense clouds, cloud cores, protostellar envelopes and protoplanetary disks. Up to 80% of the available…
The Spitzer ice legacy: Ice evolution from cores to protostars
Karin I. Oberg, A. C. Adwin Boogert, Klaus M. Pontoppidan +5
Ices regulate much of the chemistry during star formation and account for up to 80% of the available oxygen and carbon. In this paper, we use the Spitzer c2d ice survey, compliment…
The Bolocam Galactic Plane Survey V: HCO+ and N2H+ Spectroscopy of 1.1 mm Dust Continuum Sources
Wayne M. Schlingman, Yancy L. Shirley, David E. Bolin +8
We present the results of observations of 1882 sources in the Bolocam Galactic Plane Survey (BGPS) at 1.1 mm with the 10m Heinrich Hertz Telescope simultaneously in HCO+ J=3-2 and…
A Mid-Infrared Census of Star Formation Activity in Bolocam Galactic Plane Survey Sources
Miranda K. Dunham, Thomas P. Robitaille, Neal J. Evans +3
We present the results of a search for mid-infrared signs of star formation activity in the 1.1 mm sources in the Bolocam Galactic Plane Survey (BGPS). We have correlated the BGPS…
