The JCMT Nearby Galaxies Legacy Survey I. Star Forming Molecular Gas in Virgo Cluster Spiral Galaxies
C. D. Wilson, B. E. Warren, F. P. Israel +20
We present large-area maps of the CO J=3-2 emission obtained at the James Clerk Maxwell Telescope for four spiral galaxies in the Virgo Cluster. We combine these data with publishe…
LCDM Satellites and HI Companions - The Arecibo ALFA Survey of NGC 2903
J. A. Irwin, G. L. Hoffman, K. Spekkens +11
We have conducted a deep, complete HI survey, using Arecibo/ALFA, of a field centered on the nearby, isolated galaxy, NGC 2903, which is similar to the Milky Way in its properties.…
WASP-5b: a dense, very-hot Jupiter transiting a 12th-mag Southern-hemisphere star
D. R. Anderson, M. Gillon, C. Hellier +28
We report the discovery of WASP-5b, a Jupiter-mass planet orbiting a 12th-mag G-type star in the Southern hemisphere. The 1.6-d orbital period places WASP-5b in the class of very-h…
The effect of dust obscuration in RR Tel on optical and IR long-term photometry and Fe II emission lines
D. Kotnik-Karuza, M. Friedjung, P. A. Whitelock +4
Infrared and optical photometric and spectroscopic observations of the symbiotic nova RR Tel are used to study the effects and properties of dust in symbiotic binaries containing a…
Radio Jet-blown Neutral Hydrogen Supershells in Spiral Galaxies?
Gopal-Krishna, Judith A. Irwin
Taking a clue from the pair of HI supershells found in the Scd galaxy NGC 3556 (M 108), we propose a new mechanism for the origin of HI supershells in gas-rich massive galaxies. In…
Magnetized Protostellar Bipolar Outflows I. Self-similar model
Thibaut Lery, Richard N. Henriksen, Jason D. Fiege
We study a self-similar circulation model for protostellar bipolar outflows. The model is axisymmetric and stationary, and now includes Poynting flux. Compared to an earlier versio…
