Molecular abundance ratios as a tracer of accelerated collapse in regions of high-mass star formation
Recent observations suggest that the behavior of tracer species such as N2H+ and CS is significantly different in regions of high- and low-mass star formation. In the latter, N2H+ is a good tracer of mass, while CS is not. Observations show the reverse to be true in high-mass star formation regions....
