Study of the star-forming region L379 IRS3 in CH sub(3)OH and CS
A molecular cloud and high-velocity outflow associated with the star-forming region L379 IRS3 have been mapped in the 6 sub(-1)-5 sub(0) 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 810 super(14) cm sup...

| Zusammenfassung: | A molecular cloud and high-velocity outflow associated with the star-forming region L379 IRS3 have been mapped in the 6 sub(-1)-5 sub(0) 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 810 super(14) cm super(-2) and 410 super(-9), respectively. LVG modeling of the methanol emission constrains the gas density in the cloud to (1-4)10 super(5) cm super(-3) and the gas kinetic temperature to 20-45 K. The upper limit on the density of the high-velocity gas is 10 super(5) cm super(-3). |
