Submillimeter Dust Continuum Emission as a Probe of Protostellar Evolution

1996
The strength and spatial distribution of the (sub)millimeter continuum emission from young stellar objects (YSOs) are powerful diagnostics of the progressive decrease and condensation of circumstellar mass during protostellar evolution. In particular, the ratio of submm to bolometric luminosity may be used as a practical evolutionary indicator for ...

Origins of the 12-200 micron flux in NGC 6946 - Starlight and continuum dust emission from an SC galaxy

Astrophysical Journal, Supplement Series, 1991
Infrared maps and optical CCD images of NGC 6946, a nearly face-on spiral with evidence of active star formation, are presented. Consideration is given, at 1-3 kpc spatial scales, to the relationship of the infrared continuum to spiral and radial structure, tracers of the interstellar medium, and ionizing and nonionizing sources of stellar radiation ...

The Mass-Loss History of Carbon Stars Probed by Co Line and Dust Continuum Emission

2003
An extensive modelling of CO line emission from the circumstellar envelopes around a number of carbon stars is performed. By combining radio observations and infrared observations obtained by ISO the circumstellar envelope characteristics are probed over a large radial range.

Search for massive protostar candidates in the southern hemisphere. II. Dust continuum emission

2006
In an ongoing effort to identify and study high-mass protostellar candidates we have observed in various tracers a sample of 235 sources selected from the IRAS Point Source Catalog, mostly with δ < -30 degr, with the SEST antenna at millimeter wavelengths.

Dust temperature uncertainties hamper the inference of molecular gas masses from the dust continuum emission of high-redshift galaxies

2022
Single flux density measurements at observed-frame sub-millimeter and millimeter wavelengths are commonly used to probe dust and gas masses in galaxies. We explore the robustness of this method to infer dust mass for both star-forming and quiescent galaxies, using a series of controlled experiments on four massive haloes from the Feedback in Realistic ...
