Abstract:
The success of helioseismology is due to its capability of
measuring p-mode oscillations in the Sun. This allows us to extract information
on the internal structure and rotation of the Sun from the surface
to the core. Similarly, asteroseismology is the study of the internal structure
of the stars as derived from stellar oscillations. In this review we
highlight the progress in the observational asteroseismology, including
some basic theoretical aspects. In particular, we discuss our contributions
to asteroseismology through the study of chemically peculiar stars under
the ‘Nainital-Cape Survey’ project being conducted at ARIES, Nainital,
since 1999. This survey aims to detect new rapidly-pulsating Ap (roAp)
stars in the northern hemisphere. We also discuss the contribution of
ARIES towards the asteroseismic study of the compact pulsating variables.
We comment on the future prospects of our project in the light
of the new optical 3.6-m telescope to be installed at Devasthal (ARIES).
Finally, we present a preliminary optical design of the high-speed imaging
photometers for this telescope.
