General Description

We will perform near-infrared spectroscopy of selected intermediate-mass
 stars, which exhibit strong H_alpha emission in known star forming regions in the
 Large Magellanic Cloud (LMC). The aim of this observing run is to verify the pre-main
 sequence nature of these stars. This study has the potential to provide an original
 characterization of candidate Herbig Ae/Be stars through their near-IR spectral
 features, such as circumstellar shells, and the first solid discovery of such stars
 in the low-metallicity environment of the LMC. Our observing strategy is to perform
 SINFONI spectroscopy in the K- and H-band for three targets, selected as the most
 promising candidates, based on their H_alpha excess found earlier with ground-based
 photometry, and on recent high-resolution HST/ACS imaging. For one of the targets
 spectroscopy in the J-band will be also performed. The NIR magnitudes for our selected
 targets according to the 2MASS All-Sky Point-Sources Catalog are: Star #37: J=14.94
 mag, H=14.97 mag, K=14.99 mag. Star #157: J=15.46 mag, H=15.03 mag, K=14.57 mag.
 Star #194: J=15.53 mag, H=15.02 mag, K=14.85 mag.
