Three intermediate-mass YSOs with different properties emerging from the same natal cloud in IRAS 00117+6412
Aina Palau, A. Sanchez-Monge, G. Busquet +5
We observed with the VLA, PdBI, and SMA the centimeter and millimeter continuum, N2H+(1-0), and CO(2-1) emission associated with a dusty cloud harboring a nascent cluster with inte…
The Initial Conditions of Clustered Star Formation. II. N2H+ Observations of the Ophiuchus B Core
R. K. Friesen, J. Di Francesco, Y. Shimajiri +1
We present a Nobeyama 45 m Radio Telescope map and Australia Telescope Compact Array pointed observations of N2H+ 1-0 emission towards the clustered, low mass star forming Oph B Co…
A contracting circumbinary molecular ring with an inner cavity of about 140 AU around Ori 139-409
Luis A. Zapata, Peter Schilke, Paul Ho
Sensitive and subarcsecond resolution ( 0.7\arcsec) CHOH(7 6) line and 890 m continuum observations made with the Submillimeter Array (SMA) tow…
Formation of an O-Star Cluster by Hierarchical Accretion in G20.08-0.14 N
Roberto Galván-Madrid, Eric Keto, Qizhou Zhang +3
Spectral line and continuum observations of the ionized and molecular gas in G20.08-0.14 N explore the dynamics of accretion over a range of spatial scales in this massive star-for…
IRAS 16293: A "Magnetic" Tale of Two Cores
Ramprasad Rao, Josep Miquel Girart, Daniel P. Marrone +2
We present polarization observations of the dust continuum emission from IRAS 16293 which is a Class 0 protostar and is known to have at least two components, source A and B. These…
Outflows and Massive Stars in the protocluster IRAS 05358+3543
Adam G. Ginsburg, John Bally, Chi-Hung Yan +1
We present new near-IR H2, CO J=2-1, and CO J = 3-2 observations to study outflows in the massive star forming region IRAS 05358+3543. The Canada-France-Hawaii Telescope H2 images…
