Recently, a subset of starless cores whose thermal Jeans mass is apparently overwhelmed by the mass of the core has been identified, e.g., the core {\small L183}. In literature, massive cores such as this one are often referred to as "super-Jeans cores". As starless cores are perhaps on the cusp of forming stars, a study of their dynamics will improve our understanding of the transition from the prestellar to the protostellar phase. In the present work we use non-magnetic polytropes belonging…

CORRELATING INFALL WITH DEUTERIUM FRACTIONATION IN DENSE CORES
We present a survey of HCO + (3-2) observations pointed towards dense cores with previous measurements of N(N2D + )/N(N2H + ). Of the 26 cores in this survey, five show the spectroscopic signature of
