Identifying Previously Uncatalogued Red Variable Stars inthe Northern Sky Variability Survey

摘要

Candidate variable stars in the publicly available data of the NorthernSky Variability Survey (NSVS) were identified by data mining the 2MASSsurvey for entries that matched the following criteria: Dec. > –20.000, (J– K)> 1.2, and J.-magnitude < 7.000. A total of 1,233 such stars were identified: 1type M, 64 type M:, 26 type SR:, and 1,142 type L:, with amplitudes between0.3 magnitude and 3.4 magnitudes. Only stars not listed in the InternationalVariable Star Index (VSX) at the time of submission or not identified as variablein SIMBAD have been included.
