Filamentary Star Formation: Observing the Evolution toward Flattened Envelopes
Katherine Lee, Leslie Looney, Doug Johnstone +1
Filamentary structures are ubiquitous from large-scale molecular clouds (few parsecs) to small-scale circumstellar envelopes around Class 0 sources (~1000 AU to ~0.1 pc). In partic…
An Observed Lack of Substructure in Starless Cores II: Super-Jeans Cores
Scott Schnee, Sarah Sadavoy, James Di Francesco +2
We present SMA and CARMA continuum and spectral line observations of five dense cores located in the Perseus and Ophiuchus molecular clouds whose masses exceed their thermal Jeans…
The Small-Scale Physical Structure and Fragmentation Difference of Two Embedded Intermediate Mass Protostars in Orion
Tim van Kempen, Steve Longmore, Doug Johnstone +2
Intermediate mass protostars, the bridge between the very common solar-like protostars and the more massive, but rarer, O and B stars, can only be studied at high physical spatial…
The JCMT Legacy Survey of the Gould Belt: mapping 13CO and C18O in Orion A
J. V. Buckle, C. J. Davis, J. Di Francesco +31
The Gould Belt Legacy Survey will map star-forming regions within 500 pc, using HARP (Heterodyne Array Receiver Programme), SCUBA-2 (Submillimetre Common-User Bolometer Array 2) an…
