This is a wonderful and particular EA system. The GPX-TF8C-4068 (UCAC4 746-024309 in Cassiopeia) is a Algol-type system with the peculiar RS behavior. The class prototype is RS CVn. These particular stars has an important chromospherical activity and a strong magnetic field. Due the magnetic activity, the most important thing that you can see in […]
A new EA system has been discovered with the telescope of Astronomical Observatory of Universisty of Siena. This is the UniSi_V112 (UCAC4 734-075544 in Cepheus). The star was discovered on october 19, 2018 observing another target.The work was possible thank’s to the collaboration of Alessandro Marchini and Riccardo Papini. Period is one of the longest […]
Another beautiful and particular EA system, GPX-TF8D-582 7 (GSC 04047-0214 in Cassiopeia), has been discovered during the GPX survey and submitted to VSX by P. Benni, A. Burdanov, F. Salvaggio, A. Marchini, R. Papini. The system, looking the lightcurve, seems near the border to two types: EA and EB. MAgnitude variation goes from 11.09 to […]
