Salvaggio, A. Marchini, R. Papini. Magnitude variation goes from 14.67 to 14.87 V. The related period of the spot migration wave is […]

A new EW variable star system has been discoverted. This is LiceoIrisVersari_V1 (UCAC4 563-038465 in Gemini) named after the High School Liceo Iris Versari, located in Casano Maderno, (MB), Italy. The first detection was made with the telescope of Astronomical Observatory of University of Siena by Alessandro Marchini, Fabio Salvaggio, Riccardo Papini during the Christmas […]

This is the GPX-TF8C-2775 (GSC 03699-01804 in Perseus), a new EW system discovered during the GPX survey and submitted to VSX by P. Benni, A. Burdanov, F. Salvaggio, A. Marchini, R. Papini.  The most interesting feature of this system is the very long time period related to the typology (mainly 0.3-05 d) Magnitude variation goes […]

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 […]

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 […]
