Flickering in the Magnetic CV Star AM Herculis

Astrophysics and Space Science, 2005
In this study, we present a photometric study of AM Her, a prototype of a class of magnetic CVs. Optical photometry of AM Her was obtained using the Russian—Turkish 1.5 m telescope at TUBITAK National Observatory (TUG) in August 2003. The R band light curve of the system shows two maxima and two minima during one orbital cycle. In both observing nights

Simultaneous spectroscopy and photometry of the AM Herculis-like star H0139-68

Publications of the Astronomical Society of the Pacific, 1983
We obtained one orbital cycle of spectroscopic and photometric data for the newly discovered AM Herculis-like object H0139-68. The light curve shows a flat-bottomed minimum and a flat-topped maximum, with decreasing amplitude toward shorter wavelengths. The spectrum shows strong emission lines of H, He I, and He II.
