Abstract content <br> (Max 300 words)
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. Some of
them have been found to pulsate in radial and non-radial modes. V351 Ori has been fond to pulsate
in different frequencies ranging from 11 c/d to 30 c/d in radial mode. We observed this star over
three weeks in December 2012 and February2013. Before 1986 the brightness of this star showed
changes due to dust obscuration. However after 1986 such variability disappeared. The lack of
variability was explained as the disappearance of obscuring material around the star. Now we wish
to compare the pulsation frequencies measured at different times to see if there are any systematic
changes and whether we can model the change.
