Inner Structure of Protostellar Collapse Candidate B335 Derived from Millimeter-Wave Interferometry
We present a study of the density structure of the protostellar collapse candidate B335 using continuum observations from the IRAM Plateau de Bure Interferometer made at wavelengths of 1.2 mm and 3.0 mm. We analyze these data, which probe spatial scales from 5000 AU to 500 AU, directly in the visibility domain by comparison to synthetic observations constructed from models that assume different...

We present a near-infrared extinction study of the dark globule B335, a protostellar collapse candidate, using data from HST/NICMOS and the W.M. Keck Observatory. These data allow a new quantitative test of the “inside-out” collapse model previously proposed to explain molecular line profiles observed toward this region. We find that the shape of the density profile is well matched by the colla...
متن کاملThe structure of protostellar envelopes derived from submillimeter continuum images
High dynamic range imaging of submillimeter dust emission from the envelopes of eight young protostars in the Taurus and Perseus star-forming regions has been carried out using the SCUBA submillimeter camera on the James Clerk Maxwell Telescope. Good correspondence between the spectral classifications of the protostars and the spatial distributions of their dust emission is observed, in the sen...
متن کاملProtostellar Collapse Induced by Compression
We present numerical simulations of the evolution of low-mass, isothermal, molecular cores which are subjected to an increase in external pressure Pext. If Pext increases very slowly, the core approaches instability quite quasistatically. However, for larger (but still quite modest) dPext/dt a compression wave is driven into the core, thereby triggering collapse from the outside in. If collapse...

We present subarcsecond resolution dust continuum observations of the protostellar collapse candidate B335 made with the IRAM Plateau de Bure Interferometer at wavelengths of 1.2 and 3.0 mm. These observations probe to < 100 AU size scales and reveal a compact source component that we identify with a circumstellar disk. We analyze these data in concert with previous lower resolution interferome...
