Millimeter and Far-IR Study of the IRDC SDC 341.232-0.268

Rubio, M.; Firpo, V.; Cappa, C. E. +3 more

We analyze the molecular gas and dust associated with the infrared dark cloud SDC 341.232-0.268 in order to investigate the characteristics and parameters of the gas, determine the evolutionary status of four embedded EGO candidates, and establish possible infall or outflow gas motions. We base our study on ¹²CO(2-1), ¹³CO(2-…

The IRAS 08589-4714 star-forming region

Gómez, M.; Rubio, M.; Cappa, C. E. +3 more

We present an analysis of the IRAS 08589-4714 star-forming region. This region harbors candidate young stellar objects identified in the WISE and Herschel images using color index criteria and spectral energy distributions (SEDs). The SEDs of some of the infrared sources and the 70 µm radial intensity profile of the brightest source are mode…

A submillimeter study of the IR dust bubble S 21 and its environs

Rubio, M.; Borissova, J.; Firpo, V. +4 more

Based on the molecular emission in the ¹²CO(2-1) and ¹³CO(2-1) lines, and on the continuum emission in the MIR and FIR towards the S 21 IR dust bubble, we analyze the physical characteristics of the gas and dust linked to the nebula and the presence of young stellar objects (YSOs) in its environs. The line emission reveals a …
