A search for variability of TiO bands in the spectrum of the T Tauri star V410 Tau.
Abstract
Low resolution, high signal-to-noise ratio CCD-spectroscopy of the T Tau star V410 Tau in the region of TiO bands near 7100 Å was carried out in 1991/92. Relationship between V-magnitude of the star and intensity of the TiO bands was found, in favour of the hypothesis of cool spots on the star's surface. The relationship is modelled using synthetic spectra of the photosphere and the cool spot.
