The Prospects of Pulsating Stars Studies with the International Liquid Mirror Telescope
Abstract
The Hertzsprung-Russell diagram is populated with pulsating stars of many different kinds and flavours. Asteroseismology uses the pulsations of these stars to gain information about their interior, which is needed to improve our understanding of stellar evolution. During the last decade, asteroseismic studies have greatly boosted thanks to space missions like Microvariability and Oscillations of Stars (Walker et al., 2003), COnvection ROtation and Planetary Transits (CoRoT; Auvergne et al. 2009), Kepler/K2 (Borucki et al., 2010), and Transiting Exoplanet Survey Satellite (TESS; Ricker et al. 2015). These missions have collected nearly uninterrupted photometric time series with a precision down to a few μ mag and a total time base of up to 4 years. TESS is the only one of these missions that is still collecting data and that is covering the largest part of the sky and hence will have targets in common with the strip of the sky that is monitored by the 4-m International Liquid Mirror Telescope from the Devasthal Observatory in northern India. In this paper, we try to find out for which types of pulsating stars the ILMT observations are expected to be most appropriate for asteroseismic studies.
