Initial conditions for star formation in clusters: physical and kinematical structure of the starless core Oph A-N6
Tyler L. Bourke, Philip C. Myers, Paola Caselli +4
We present high spatial (<300 AU) and spectral (0.07 km/s) resolution Submillimeter Array observations of the dense starless cluster core Oph A-N6, in the 1 mm dust continuum and t…
Spitzer observations of Bow Shocks and Outflows in RCW 38
E. Winston, S. J. Wolk, T. L. Bourke +3
We report Spitzer observations of five newly identified bow shocks in the massive star-forming region RCW 38. Four are visible at IRAC wavelengths, the fifth is visible only at 24…
The Structure of the Star-forming Cluster RCW 38
Elaine Winston, Scott J. Wolk, Tyler Bourke +3
We present a study of the structure of the high mass star-forming region RCW~38 and the spatial distribution of its young stellar population. Spitzer IRAC photometry 3-8um are comb…
The enigmatic core L1451-mm: a first hydrostatic core? or a hidden VeLLO?
Jaime E. Pineda, Héctor G. Arce, Scott Schnee +9
We present the detection of a dust continuum source at 3-mm (CARMA) and 1.3-mm (SMA), and 12CO(2-1) emission (SMA) towards the L1451-mm dense core. These detections suggest a compa…
Arcsecond resolution images of the chemical structure of the low-mass protostar IRAS 16293-2422
Jes K. Jorgensen, Tyler L. Bourke, Quang Nguyen Luong +1
It remains a key challenge to establish the molecular content of different components of low-mass protostars, like their envelopes and disks, and how this depends on the evolutiona…
Detection of a Bipolar Molecular Outflow Driven by a Candidate First Hydrostatic Core
Michael M. Dunham, Xuepeng Chen, Hector G. Arce +3
We present new 230 GHz Submillimeter Array observations of the candidate first hydrostatic core Per-Bolo 58. We report the detection of a 1.3 mm continuum source and a bipolar mole…
