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…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
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…
