The Dust Emissivity Spectral Index in the Starless Core TMC-1C (2009)
Schnee, Scott, Enoch, Melissa, Noriega-Crespo, Alberto, Sayers, Jack, Terebey, Susan, Caselli, Paola, ...
In this paper we present a dust emission map of the starless core TMC-1C taken at 2100 microns. Along with maps at 160, 450, 850 and 1200 microns, we study the dust emissivity spectral index from the...
IRAS 16293: A "Magnetic" Tale of Two Cores (2009)
Rao, Ramprasad, Girart, Josep Miquel, Marrone, Daniel P., Lai, Shih-Ping, Schnee, Scott
We present polarization observations of the dust continuum emission from IRAS 16293 which is a Class 0 protostar and is known to have at least two components, source A and B. These measurements were...
Testing the Evolutionary Sequence of High-Mass Protostars with CARMA (2009)
Schnee, Scott, Carpenter, John M.
We present 1" resolution Combined Array for Research in Millimeter-wave Astronomy (CARMA) observations of the 3 mm continuum and 95 GHz CH_3OH masers toward 14 candidate high-mass protostellar...
The Effect of Line-of-Sight Temperature Variation and Noise on Dust Continuum Observations (2009)
Shetty, Rahul, Kauffmann, Jens, Schnee, Scott, Goodman, Alyssa A., Ercolano, Barbara
We investigate the effect of line-of-sight temperature variations and noise on two commonly used methods to determine dust properties from dust-continuum observations of dense cores. One method...
The Effect of Line of Sight Temperature Variation and Noise on Dust Continuum Observations (2009)
Shetty, Rahul, Kauffmann, Jens, Schnee, Scott, Goodman, Alyssa A., Ercolano, Barbara
We investigate the effect of line of sight temperature variations and noise on two commonly used methods to determine dust properties from dust continuum observations of dense cores. One method...
The Effect of Noise on the Dust Temperature - Spectral Index Correlation (2009)
Shetty, Rahul, Kauffmann, Jens, Schnee, Scott, Goodman, Alyssa A.
We investigate how uncertainties in flux measurements affect the results from modified blackbody SED fits. We show that an inverse correlation between the dust temperature T and spectral index (beta)...
The Gas Temperature of Starless Cores in Perseus (2008)
Schnee, Scott, Rosolowsky, Erik, Foster, Jonathan, Enoch, Melissa, Sargent, Anneila
In this paper we study the determinants of starless core temperatures in the Perseus molecular cloud. We use NH3 (1,1) and (2,2) observations to derive core temperatures (T_kin) and data from the...
