Massive Star Formation in the LMC. I. N159 and N160 Complexes
  We present images and spectral energy distributions (SEDs) of massive young
stellar objects (YSOs) in three star-forming H II regions of the Large
Magellanic Cloud: N159A, N159 Papillon, and N160. We use photometry from
SOFIA/FORCAST at 25.3--37.1 um to constrain model fits to the SEDs and
determine luminosities, ages, and dust content of the embedded YSOs and their
local environments. By placing these sources on mid-infrared color-magnitude
and color-color diagrams, we analyze their dust properties and consider their
evolutionary status. Since each object in the FORCAST images has an obvious
bright near-infrared counterpart in Spitzer Space Telescope images, we do not
find any evidence for new, very cool, previously-undiscovered Class 0 YSOs.
Additionally, based on its mid-infrared colors and model parameters, N159A is
younger than N160 and the Papillon. The nature of the first extragalactic
protostars in N159, P1 and P2, is also discussed.
