cds-question@unistra.frmagellanic-cloudsinfrared-photometryh-ii-regionsyoung-stellar-objectsWe 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{mu}m 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.2017ApJ...834..122Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/834/122CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+A/381/941 : HST photometry of stars in N160A (Heydari-Malayeri+, 2002)J/A+A/422/129 : JHKs photometry in N159 (LMC) (Meynadier+, 2004)J/A+A/453/517 : JKs photometry of N159A (Testor+, 2006)J/AJ/135/2323 : H{alpha} stars and HH objects near BRCs (Ikeda+, 2008)J/AJ/138/510 : Spectral classification of N159/N160 stars (Farina+, 2009)J/ApJ/699/150 : Spectral classifications of Massive YSOs in LMC (Seale+, 2009)J/ApJ/707/1417 : HST view of YSOs in the LMC (Vaidya+, 2009)J/ApJS/184/172 : High- and intermediate-mass YSOs in the LMC (Gruendl+, 2009)J/ApJ/715/310 : Early stages of star formation in IRDCs (Rathborne+, 2010)J/A+A/537/A146 : Stellar models with rotation, Z=0.014 (Ekstrom+, 2012)J/A+A/542/A66 : YSOs in 9 LMC star forming regions (Carlson+, 2012)J/ApJ/779/79 : Galactic CHaMP.
