Abstract: | With the resounding success of helioseismology in determining the interior structure and rotation of the Sun, and in providing
unprecedented studies of the interaction of pulsation and magnetic fields in the solar atmosphere, astronomers have been delighted,
after decades of disappointing attempts, with the recent discovery of solar-like oscillations in ξ Hya, β Hyi, α Cen A and
B, η Boo, ν Ind, ζ Her, δ Eri, HD 20794, HD 160191, and others as this list is growing rapidly. There is now true seismology
of some solar-like stars. Asteroseismology also studies stars with a wide variety of interior and surface conditions. For
two decades asteroseismic techniques have been applied to many pulsating stars across the HR diagram. This review describes
some recent developments for some selected classes of pulsating stars other than the solar-like oscillators. |
