Multiwavelength Observations of MWC 297: Constraints on Disk Inclination and Mass Outflow

Abstract MWC 297 is a young, early-type star driving an ionized outflow and surrounded by warm, entrained dust. Previous analyses of near- mid-IR interferometric images suggest that the emission at these wavelengths arises from compact accretion disk with moderate ( i < 40°) inclination. We have obtained 5–40 μ m FORCAST on SOFIA, as well near-infrared spectra acquired SpeX IRTF radio data VLA BIMA, supplemented archival Herschel/PACS SPIRE. The images, combined data, indicate lobes are aligned nearly north–south separated. Simple geometrical modeling suggests has inclination 55° ± 5°, in disagreement results analyses.
