Detection of 228 variable stars in NGC 281
Listed in IVOA Registry (Virtual Observatory)
We identify 228 periodic variables in the region of young open cluster NGC 281 using time series photometry carried out from 1 m class ARIES telescopes, Nainital.
Description
The cluster membership of these identified variables is determined on the basis of colour-magnitude, two colour diagrams, and kinematic data. A total of 81 variable stars are found to be members of the cluster NGC 281.
Of 81 variables, 30 and 51 are probable main-sequence and pre-main-sequence members, respectively. This study classifies main-sequence variable stars into different variability types according to their periods of variability, shape of light curves, and location in the Hertzsprung-Russell diagram. These identified main-sequence variables could be {beta} Cep, {delta} Scuti, slowly pulsating B type, and new class variables.

Among 51 pre-main-sequence variables, majority of them are weak line T Tauri stars. The remaining 147 variables could belong to the field population. The variability characteristics of the field population indicate that these variables could be RR Lyrae, {delta} Scuti, and binaries-type variables.
