Periods in a 87 Years Light Curve of the Symbiotic Star MWC 560

Elia M. Leibowitz, Liliana Formiggini

We have constructed a visual light curve of the symbiotic star MWC covering the last 87 years of its history. The data were assembled from the literature and from the AAVSO data ba…

The peculiar light curve of the Symbiotic Star AX Per of the last 125 years

Elia M. Leibowitz, Liliana Formiggini

We analyze the last 125 years optical light curve of the symbiotic star AX Per through some remarkable correlations that we discovered in its power spectrum. The data were assemble…

The historical light curve of the symbiotic star AG Draconis: intense, magnetically induced cyclic activity

Liliana Formiggini, Elia M. Leibowitz

We analyze an optical light curve of the symbiotic system AG Draconis covering the last 120 years of its history. During the first 32 years the system was in a quiescence state. Ar…

Period switching in the symbiotic star BX Mon

Elia M. Leibowitz, Liliana Formiggini

We report on a detailed analysis of the optical light curve of the symbiotic system BX Mon, the data of which were gathered from the literature. The light curve covers the period D…

Discovery of the 1.80 hr Spin Period of the White Dwarf of the Symbiotic System BF Cyg

Liliana Formiggini, Elia M. Leibowitz

We report on the discovery of a coherent periodicity in the B light curve of the symbiotic star BF Cyg. The signal was detected in some sections of the light curve of the star reco…

Activity cycle of the giant star of Z Andromedae and its spin period

Elia M. Leibowitz, Liliana Formiggini

We have reanalyzed the long-term optical light curve (LC) of the symbiotic star Z Andromedae, covering 112--yr of mostly visual observations. Two strictly periodic and one quasi-pe…
