Abstract
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 8×1014 cm−2 and 4×10−9, respectively. LVG modeling of the methanol emission constrains the gas density in the cloud to (1–4)×105 cm−3 and the gas kinetic temperature to 20–45 K. The upper limit on the density of the high-velocity gas is 105 cm−3.
