Abstract:
This poster presents a method to determine the evolutionary stage of a protostar based on the topology of the velocity field in the gas that surrounds it. By comparing the velocity field of an observed protostellar environment to the velocity fields of an ensemble of simulated protostars, it is possible to determine the age of the observed protostar. Because the simulation contains so many stars, it is possible to statistically look at the evolution in different mass bins, in different types of environment or at stars with different multiplicity.
