Hot molecular cores, sites of high mass star formation
Published online by Cambridge University Press: 25 May 2016
Abstract
We model the flux-density distribution of hot molecular cores as in-falling envelopes of gas and dust onto a central massive star. The envelopes are heated by both the stellar luminosity and the accretion luminosity. We find that, in order to reproduce the observed fluxes, these objects require high mass accretion rates Ṁ ≃ 10−4−3 M⊙yr−1 infalling onto central late B-type stars. We discuss the implications of this intense accretion phase on the formation of massive stars.
