Photometric study of hot Algol-type binaries with long cycles
J. Garcés, R. E. Mennickent, J. PetrovÃc +6
Double periodic variables (DPVs) are hot Algol-type interacting binary systems with an orbital and a long photometric cycle. The origin of the latter may be related to cyclic struc…

The vanishing of the long photometric cycle in AU Monocerotis
L. Celedón, R. E. Mennickent, D. BarrÃa +2
Double periodic variables (DPVs) are a group of semi-detached interacting binaries that exhibit a long photometric cycle with an average length of times the orbital period…

Non-thermal radio emission in Sakurai's Object
Marcin Hajduk, Peter A. M. van Hoof, Albert A. Zijlstra +5
The very late thermal pulse (VLTP) affects the evolution of 20\% of 1--8\, stars, repeating the last phases of the red giant within a few years and leading t…
