“Developing a Chemical Evolutionary Sequence for Starless Cores”


Starless Cores are the earliest observable phase of low-mass star formation. Studies of this incipient phase reveal the mass fragmentation scale for star formation as well as the initial conditions for disk and protostar formation. I shall discuss results from a survey to constrain the physical state of a sample of 25 starless cores using dust continuum radiative transfer and molecular maps. I will show that our understanding of the astrochemistry in these regions is an essential astrophysical tool for developing a chemical evolutionary sequence for starless cores. I shall also highlight current astrochemical problems related to the starless core phase.
