X-ray response to disc evolution in two γCas stars

The Hα emission of a set of southern γCas stars was monitored since 2019, with the aim of detecting transition events and examining how their peculiar X-ray emission would react in such cases. Two stars, namely HD 119682 and V767 Cen, were found to display slowly decreasing disc emissions. These dec...
