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 pulsator of the B type, $beta$
Cep and $delta$ Scuti stars. Fourteen main-sequence stars could be new class
variables as discussed by Mowlavi et al. (2013) and Lata et al. (2014). The age
and mass of pre-main-sequence variables are found to be $lesssim$ 5 Myr and in
the mass range of 0.5 to 2.8 M$_{odot}$, respectively. These pre-main-sequence
stars could be T-Tauri variables. We have found 5 and 2 of 23 PMS variables as
classical T-Tauri stars and Herbig Ae/Be stars, respectively, whereas 16 PMS
stars are classified as weak-line T Tauri stars.
