PREDNASAJUCI / LECTURER : J. Vos, I. Pelisoli, J. Budaj, N. Reindl, et al. NAZOV / TITLE : Looking into the cradle of the grave: a young post-merger hot subdwarf? ABSTRAKT / ABSTRACT : We will present a strange object discovered recently by Joris Vos and collaborators. It looks like an sdB star. However: -its hydrogen lines are variable, very shallow and sometimes featuring three absorption peaks -He lines are also very broad and shallow -it has a strong and broad CaIIK line not seen in such hot stars -Halpha has an apparent emission core We will briefly discuss various scenarios which might be responsible for this behaviour.
