Herschel observations of two candidates First Hydrostatic Cores in Perseus
Stefano Pezzuto INAF - IAPS, Roma, IT | |
| In this contribution I present the results of modeling the SED of two interesting sources found in the Perseus star-forming region observed with Herschel. The physical properties of the dusty envelopes show many features that suggest that these sources are in a very early stage of their formation. We propose them as two new candidates to be first hydrostatic cores (FHSC). The FHSC stage represents the very early phase in the formation of the stellar nucleus at the center of a collapsing core. This phase begins when the infalling matter in the inner part of a core becomes optically thick so reaching for the first time an hydrostatic equilibrium. A recent paper based on SMA observations puts forward additional evidence on the very young nature of these sources. | |
