Postdoctoral Position On Massive Stars and Circumstellar Environments

Dr. Pat Morris

NASA Herschel Science Center
M/S 100-22 Caltech
Pasadena, CA, USA

A post-doctoral research fellowship is available at the Infrared Processing and Analysis Center on the California Institute of Technology campus in Pasadena, California. The successful applicant will work with Drs. Patrick Morris and Schuyler Van Dyk on mid-infrared observations (spectroscopy and imaging) obtained with the Spitzer Space Telescope, archival Infrared Space Observatory spectroscopy, and ground-based observations of the circumstellar environments of evolved massive stars. The research emphasizes the formation and destruction of dust over epochs of mass loss through stellar winds progressively enriched with CNO-processed material from the stellar cores. The research also involves extension of a successful program to locate new, "hidden" Population I Wolf-Rayet stars in the Milky Way and characterizing their environments in the thermal infrared regime, also using data obtained with the Spitzer Space Telescope. The fellow would assist with follow-up spectroscopic observations of candidate stars using the Palomar 5-m and other large telescopes. It is desired that the applicant have an interest in stellar and observational infrared astronomy, massive star evolution, the formation and processing of circustellar dust and feedback with the interstellar medium. The position is initially funded for two years. Applicants should submit a curriculum vitae, list of publications, and names of and contact information for two references to Dr. Pat Morris at the above address, or to, by 2007 Oct 1 to receive full consideration.

Caltech is an Affirmative Action/Equal Opportunity Employer. Women, Minorities, Veterans, and Disabled Persons are encouraged to apply.
