2014/12/9
Results are presented for the He emission in 31 CTTS from the Taurus-Auriga molecular cloud spanning two orders of magnitude in the mass accretion rate, and for the Fe emission in DR Tau, based on a s...
Models and observations of the millimeter and submillimeter molecular line emission of bright -rimmed clouds
