The c2d Spitzer spectroscopic survey of ices around low-mass young stellar objects II: CO2
Klaus M. Pontoppidan, A. C. A. Boogert, Helen J. Fraser +6
This paper presents Spitzer-IRS spectroscopy of the CO2 15.2 micron bending mode toward a sample of 50 embedded low-mass stars in nearby star-forming clouds, taken mostly from the…
Implications for the Origin of GRB 070201 from LIGO Observations
LIGO Scientific Collaboration, K. Hurley
We analyzed the available LIGO data coincident with GRB 070201, a short duration hard spectrum gamma-ray burst whose electromagnetically determined sky position is coincident with…
Dielectronic recombination and stability of warm gas in AGN
Susmita Chakravorty, Ajit K. Kembhavi, Martin Elvis +2
Understanding the thermal equilibrium (stability) curve may offer insights into the nature of the warm absorbers often found in active galactic nuclei. Its shape is determined by f…
An Unbiased Survey of 500 Nearby Stars for Debris Disks: A JCMT Legacy Program
B. C. Matthews, J. S. Greaves, W. S. Holland +28
We present the scientific motivation and observing plan for an upcoming detection survey for debris disks using the James Clerk Maxwell Telescope. The SCUBA-2 Unbiased Nearby Stars…
Photodesorption of CO ice
Karin I. Oberg, Guido W. Fuchs, Zainab Awad +4
At the high densities and low temperatures found in star forming regions, all molecules other than H2 should stick on dust grains on timescales shorter than the cloud lifetimes. Ye…
Desorption of hot molecules from photon irradiated interstellar ices
J. D. Thrower, D. J. Burke, M. P. Collings +10
We present experimental measurements of photodesorption from ices of astrophysical relevance. Layers of benzene and water ice were irradiated with a laser tuned to an electronic tr…
