How Starless Are Starless Cores?
Scott Schnee, James Di Francesco, Melissa Enoch +3
In this paper, we present the results of CARMA continuum and spectral line observations of the dense core Per-Bolo 45. Although this core has previously been classified as starless…
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…
Herschel Observations of a Potential Core Forming Clump: Perseus B1-E
S. I. Sadavoy, J. Di Francesco, Ph. Andre +17
We present continuum observations of the Perseus B1-E region from the Herschel Gould Belt Survey. These Herschel data reveal a loose grouping of substructures at 160 - 500 micron n…
A High Resolution Study of the HI-H2 Transition across the Perseus Molecular Cloud
Min-Young Lee, Snezana Stanimirovic, Kevin A. Douglas +12
To investigate the fundamental principles of H2 formation in a giant molecular cloud (GMC), we derive the HI and H2 surface density (Sigma_HI and Sigma_H2) images of the Perseus mo…
Filaments and ridges in Vela C revealed by Herschel: from low-mass to high-mass star-forming sites
Tracey Hill, Frederique Motte, Pierre Didelon +29
We present the first Herschel PACS and SPIRE results of the Vela C molecular complex in the far-infrared and submillimetre regimes at 70, 160, 250, 350, and 500 um, spanning the pe…
Some Systematics of Galactic Globular Clusters
Sidney van den Bergh
The global properties of all known Galactic globular clusters are examined. The relationship between the luminosities and the metallicities of Galactic globular clusters is found t…
