We present a new study of the Z~Cam-type eclipsing cataclysmic variable AY~Piscium with the aim of determining the fundamental parameters of the system and the structure of the acc…
Revisiting FS Aurigae and its triple cataclysmic variable system hypothesis
Carlos E. Chavez, Andres Aviles, Nikolaos Georgakarakos +4
A very long term variability (VLPP), with period of 875 days, was observed in the long-term light curve of FS Aurigae in 2011. This periodicity was calculated on 6 cycles. We re-ex…
