  • 摘要:We presentHKspectra of three sources located in the N 66 region of the Small Magellanic Cloud. The sources display prominent stellar Brγand extended H2emission, and exhibit infrared excesses atλ> 2μm. Based on their spectral features, and photometric spectral energy distributions, we suggest that these sources are massive young stellar objects. The findings are interpreted as evidence of on-going high mass star formation in N 66.
