Variability of CHXR 20: accretion, extinction, spots or a companion?
Published online by Cambridge University Press: 06 January 2014
Abstract
We study the photometric variability of a pre-main sequence star (K6, 0.9M⊙) CHXR 20. We test several scenarios for the variability including variable accretion, variable extinction, cool and hot spots on the stellar surface and the presence of a potential companion.
