Probing the Nature of Intermediate-Mass Star Formation Regions at 37µm
Abstract
Our team is investigating a flux-limited sample of intermediate-mass star-forming regions (IMSFRs; forming stars up to early-B) to understand what governs the transition from low-mass to high-mass star formation. We propose FORCAST 37 micron imaging of eight bright, compact objects drawn from an all-sky sample of several hundred. Photometry at 37 microns will allow us to 1) identify young stellar objects with rising SEDs that may be faint or confused in WISE 22 micron data, 2) determine the intensity of the radiation field in each object by properly modeling the SEDs, which are degenerate at wavelengths < 25 microns, 3) model the bolometric luminosities using data at the longest possible wavelengths while still having the angular resolution to avoid confusion with high Galactic backgrounds. To facilitate scheduling we provide a list of 25 possible targets and request 3.3 hours to observe any 8 targets.
