I present analyses of optical photometric, spectroscopic and X-ray observations of binary, V1147 Tau and polarimetric observations of other 43 BY Dra type active stars. The continuous photometric monitoring of active stars will leads to study short term as well as long term variations. The long term photometry and analysis of the light curves help to study the different level of activity, the nature of light variability and possible periodicity. The optical spectroscopy revealed that H alpha is present in emission of V1147 Tau, indicating a high levl of chromospheric activity. The polarization values of 43 stars in B, V, R, and I bands decrease towards longer wavelengths, which indicates the possibility of sources of linear polarization as magnetic intensification arise due to stellar spots and as scattering arise due to the thin circumstellar material. The x-ray light curve was found to be rotationally modulated and was anticorrelated with optical light curves observed at quasi-simultaneous epochs. At the end of the talk, I will discuss the research plan of other type active stars during the PDF
