AKARI Infrared Camera Survey of the Large Magellanic Cloud. II. The Near-infrared Spectroscopic Catalog
Onaka, Takashi; Ita, Yoshifusa; Sakon, Itsuki +4 more
We performed a near-infrared spectroscopic survey toward an area of ~10 deg2 of the Large Magellanic Cloud (LMC) with the infrared satellite AKARI. Observations were carried out as part of the AKARI Large-area Survey of the Large Magellanic Cloud (LSLMC). The slitless multi-object spectroscopic capability of the AKARI/IRC enabled us to …
Efficient Selection and Classification of Infrared Excess Emission Stars Based on AKARI and 2MASS Data
Zeng Li, Jin; Rector, Travis A.; Huang, Ya Fang +1 more
The selection of young stellar objects (YSOs) based on excess emission in the infrared is easily contaminated by post-main-sequence stars and various types of emission line stars with similar properties. We define in this paper stringent criteria for an efficient selection and classification of stellar sources with infrared excess emission based o…
Twenty-five Subarcsecond Binaries Discovered by Lunar Occultations
Cusano, F.; Richichi, A.; Fors, O. +1 more
We report on 25 subarcsecond binaries, detected for the first time by means of lunar occultations in the near-infrared (near-IR) as part of a long-term program using the ISAAC instrument at the ESO Very Large Telescope. The primaries have magnitudes in the range K = 3.8-10.4, and the companions in the range K = 6.4-12.1. The magnitude differences …
