Observations and Modeling of the 2-25 μm Emission from High-Mass Protostellar Object Candidates

摘要: This is a report on detailed modeling of young high-mass protostellar candidates during their most embedded and obscured phases. We performed narrowband mid-infrared imaging three candidate objects in G11.94-0.62, G29.96-0.02, G45.07+0.13 at Gemini Observatory using the Thermal-Region Camera Spectrograph (T-ReCS). The sources were imaged through up to 11 filters, sampling SEDs over entire 2-25 μm infrared range. For first time, we have fit observed massive protostars with models that take into account departures from spherical symmetry infalling envelopes. In this way, been able derive physical parameters for these earliest stages stellar life. Our suggests star formation can proceed way very similar low-mass stars.
