UniSi_V114: new EW system

The UniSi_V114 (GSC 01356-00864 in Gemini) was discovered at the telescope of Astronomical observatory of University of Siena over two years ago by A. Marchini, R. Papini and F. Salvaggio. Due the numbers of target and the bad weather, we needed help for the follow-up. It came from friends Massimo Banfi and Pietro Aceti from […]

UniSi_V113

UniSi_V113: new EW system

This one was VERY hard. Due the presence of a star at 11″ with a similar magnitude from the target, was really difficult to deblend the ASAS-SN survey’s data. This is the UniSi_V113 (UCAC4 763-005062 in Cassiopeia) and was firstly discovered on October 2017 at the telescope of Astronomical Observatory of University of Siena by […]

GPX-TF8C-4068

GPX-TF8C-4068

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 […]
