Much observational work has been done in recent years to increase the numbers of known PMS pulsating stars. However, no satisfactory asteroseismological solution exists specially for Delta Scuti stars. The unsolved problems constitute challenges for both stellar pulsation and stellar evolution. V351 Ori is a member of the Herbig Ae stars that are characterized by large infrared excess, emission in hydrogen lines and non periodic photometric and spectroscopic variability. V351 Ori has been found to pulsate in different frequencies of radial mode and possible existence of non-radial mode is also…mehr

Produktbeschreibung
Much observational work has been done in recent years to increase the numbers of known PMS pulsating stars. However, no satisfactory asteroseismological solution exists specially for Delta Scuti stars. The unsolved problems constitute challenges for both stellar pulsation and stellar evolution. V351 Ori is a member of the Herbig Ae stars that are characterized by large infrared excess, emission in hydrogen lines and non periodic photometric and spectroscopic variability. V351 Ori has been found to pulsate in different frequencies of radial mode and possible existence of non-radial mode is also suggested. The main aim of this book is to carry out time series multicolour photometry of Herbig Ae star V351 Orionis (using 0.5 M telescope) in Johnson filters (UBVRI) to study pulsations in this star. The outcome has shown different pulsation frequencies in the star. Mode identification of the star is also presented. This book will be helpful for researchers who are interested in observing variable stars.
