Abstract:
The Naini Tal-Cape survey has been initiated to search for pulsations
in chemically peculiar A and F type stars. Many of the magnetic A
peculiar type stars exhibit rapid oscillations with periods ranging from 4-16
minutes. These stars are termed as rapidly oscillating Ap stars (roAp) stars.
The oscillations are attributed to low order, high overtone p modes. In addition
to the Ap stars, this region of the HR diagram also encompasses the
non-magnetic 'Am' or metallic lined stars. Some of these Am stars exhibit low
overtone 6 Scuti type pulsations. The scientific motivation for a study of these
oscillations is discussed along with the results on the variables discovered from
the survey.
