Wednesday 14 Jun 2017: What can the SEDs of first hydrostatic core candidates reveal about their nature?

The first hydrostatic core (FHSC) is the first stable object to form in simulations of early star formation. Although several candidate FHSCs have been reported, this stage has yet to be observed conclusively. We have produced synthetic spectral energy distributions (SEDs) from 3D hydrodynamical simulations of evolving pre-stellar cores for a variety of initial conditions, such as various rotation rates, and examine the differences between the corresponding SEDs.
I will present the results of fitting model SEDs to the SEDs of ten FHSC candidates and discuss the constraints this may place on the properties of the sources. These constraints then allow us to suggest which of the FHSC candidates are most likely to contain a FHSC and what rotational structures may be observed to assist in selecting targets for further observations.
