Ultra-violet processing of ices in the Rosette Nebula
Project Investigators: Jonathan Williams, Jacqueline Keane, Edwin Bergin, Elizabeth Lada, Ian Bonnell
Summary
Dense clouds provide the natal molecular inventory for the formation of stars and planets. A serious caveat through is that the majority of the focus has been directed at clouds that are not analogous to the molecular cloud from which the solar nebula formed. The Sun formed in a high-mass star-forming cloud where at least one, and most likely manly, supernova event occurred resulting in intense ultra-violet radiation throughout the cloud complex. Understanding the nature of the material in our early solar nebula means understanding an environment dominated by massive stars. The Rosette molecular cloud provides the perfect laboratory analog for the early solar nebula molecular cloud. This project is a comparative study of the ultra-violet processing of the ices toward several embedded stellar clusters in the Rosette molecular cloud
Astrobiology Roadmap Objectives:
Project Progress
This project (Proposal ID:-50146) was awarded 9.6 hours observing with the Infrared Spectrometer onboard Spitzer. Observations are currently in the queue, and will be conducted when targets are in the visibility window. To date no observations have been made.
IRAC 8 micron image of the central region of the Rosette molecular cloud showing the location of the 8 regions that will be studied with the infrared spectrometer onboard Spitzer.Mission Involvement
SpitzerAll mid-infrared (i.e. 5 to 20 microns) observations will be obtained with the Infrared Spectrometer onboard Spitzer
