Complex Molecules in the L1157 Molecular Outflow
Héctor G. Arce, Joaquín Santiago-García, Jes K. Jørgensen +2
We report the detection of complex organic molecules in the young protostellar outflow L1157. We identify lines from HCOOCH3, CH3CN, HCOOH and C2H5OH at the position of the B1 shoc…
TMC-1C: an accreting starless core
S. Schnee, P. Caselli, A. Goodman +3
We have mapped the starless core TMC-1C in a variety of molecular lines with the IRAM 30m telescope. High density tracers show clear signs of self-absorption and sub-sonic infall a…
The Evolution of Outflow-Envelope Interactions in Low-Mass Protostars
Hector G. Arce, Anneila I. Sargent
We present multi-line and continuum observations of the circumstellar environment within 10^4 AU of a sample of protostars to investigate how the effects of outflows on their immed…
Molecular Outflows in Low- and High-Mass Star Forming Regions
Hector G. Arce, Debra Shepherd, Frederic Gueth +4
We review the known properties of molecular outflows from low- and high-mass young stars. General trends among outflows are identified, and the most recent studies on the morpholog…
The COMPLETE Survey of Star-Forming Regions: Phase I Data
Naomi A. Ridge, James Di Francesco, Helen Kirk +14
We present an overview of data available for the Ophiuchus and Perseus molecular clouds from ``Phase I'' of the COMPLETE Survey of Star-Forming Regions. This survey provides a rang…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
