摘要：We present time-series photometry in the field of Stock 8 and identified 130 short-period variable stars. Twenty-eight main-sequence and 23 pre-main-sequence variables are found to be part of cluster Stock 8. The main-sequence variables are classified as slow pulsators of the B-type, β Cep, and δ Scuti stars. Fourteen main-sequence stars could be new class variables as discussed by Mowlavi et al. and Lata et al. The age and mass of pre-main-sequence variables are found to be 5Myr and in the mass range of 0.5–2.8 M e , respectively. These pre-main-sequence stars could be T-Tauri variables. We have found 5 and 2 of 23 pre-main-sequence variables as classical T-Tauri stars and Herbig Ae/Be stars, respectively, whereas 16 pre-main-sequence stars are classified as weak-line T-Tauri stars.
