AN ANALYSIS OF LONG-TERM LIGHT CURVES OF FOUR NOVALIKE VARIABLES

  • Published : 1996.12.01

Abstract

The long-term light curves of the novalikes TT Ari, KR Aur, AM Her and MV Lyr, were compiled and analysed for solar-like cyclical behaviour. The frequency analysis showed long-term cyclical modulations of the brightness of the stars, which can be ascribed to changes of the radii of the late type secondaries in order of ${\Delta}R/R{\simeq} 10^{-4}-10^{-5}$.
