Study of the star-forming region L379 IRS3 in CH3OH and CS

A molecular cloud and high-velocity outflow associated with the star-forming region L379 IRS3 have been mapped in the 6-1-50 E methanol and CS (3-2) lines using the 12-meter Kitt Peak telescope. The estimated CS column density and abundance in the molecular cloud are 8X10 cm and 4X10, respectively....

Zusammenfassung:	A molecular cloud and high-velocity outflow associated with the star-forming region L379 IRS3 have been mapped in the 6-1-50 E methanol and CS (3-2) lines using the 12-meter Kitt Peak telescope. The estimated CS column density and abundance in the molecular cloud are 8X10 cm and 4X10, respectively. LVG modeling of the methanol emission constrains the gas density in the cloud to (1--4)X10 cm and the gas kinetic temperature to 20--45 K. The upper limit on the density of the high-velocity gas is 10 cm.
