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: 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
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 […]
UniSi_V112: new EA system
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 […]
GPX-TF8D-582
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 […]
GPX-TF8D-1637
Another EA system, GPX-TF8D-1637 (GSC 04047-01243 in Cassiopeia), has been discovered during the GPX survey and submitted to VSX by P. Benni, A. Burdanov, F. Salvaggio, A. Marchini, R. Papini. Magnitude variations goes from 12.10 to 12.17 V with a secondary minima at 12.13 V. Epoch: HJD 2457676.675 Period: 1.23269 d This is the link […]
