And it’s time to back in Ophiucus, where in last May, with Alessandro Marchini and Riccardo Papini, using the telescope of Astronomical Observatory of University of Siena, discovered this new EW system: the UniSi_V107 (UCAC4 431-063476).ASAS-SN data were used to fix the period. The magnitude goes from 15.94 to 16.22 V, with a secondary minima […]
A new EA system in Gemini has been discovered from the telescope of Astronomical observatory of University of Siena. This is UniSi_V106, an EA system observed for the very first time in december 2016 and approved only today after a lot of work.The discovery has been possible with the effort of my brothers in stars […]
A new pulsading star (HADS – High Amplitude Delta Scuti star) has been discovered from the telecope of Astronomical Observatory of University of Siena with Alessandro Marchini and Riccardo Papini. First observation of this star (UCAC4 371-080438 in Ophiucus) was on May, 30 2016. In last months we had a lot of help from Unione […]
A EW new system has been discovered in Aquila: this is the UniSi_V104 (UCAC4 461-085909), worked with the telescope of Osservatorio Astronomico of University of Siena, WBRO and Banfi’s observatory in Novate (MI). The system has been discovered on June, 16 and completed thank to the work of Massimo Banfi, Alessandro Marchini and Riccardo Papini. […]
After few months passed into bad weather and difficult fields… we back with the UniSi_V103 (UCAC4 458-084855) in Aquila, a nice EW system discovered on last June, 10 by the telescope of Astronomical observatory of University of Siena with the collaboration of Davide Agnetti (Lomazzo), Alessandro Marchini and Riccardo Papini. In order to define period, […]
A new EA system has been discovered with the telescope of Astronomical Observatory of University of Siena. This is the UniSi_V102 (UCAC4 759-020853) in Cassiopeia, discovered with my brothers-in-stars Alessandro Marchini and Riccardo Papini. In order to define the period, we also used the ASAS-SN survey data. The magnitude goes from 14.68 to 15.20 V […]
A new pulsading star (HADS Type) has been discovered with the telescope of Astronomical Observatory of University of Siena. This is the UniSi_V101 (CMC15 J165027.5+015735) in Ophiucus, discovered with Alessandro Marchini and Riccardo Papini In order to define the period, we also used the ASAS-SN survey data. The magnitude goes from 17.1 to 17.4 CV. […]
A new EW system has been discovered with the telescope of the Astronomical Observatory of University of Siena: this is the GSC 04463-01015 in Cepheus. In order to define the period, we also used the ASAS-SN survey data. The magnitude goes from the 13.15 to 13,52 V Epoch: HJD 2458084.3164 Period: 0.386547 d The link to VSX […]
Another variable star system discovered! Six in a row! This is the UCAC4 760-020518 in Cassiopeia, a very nica and faint EB system discovered with Alessandro Marchini (Astronomical Observatory University of Siena), me, Riccardo Papini and Massimo Banfi (WBRO -K49) and Claudio Arena. The system is too faint to use survey due to determine the […]
And again, we did it! This is the UCAC4 662-020393 in Perseus. It’s a really faint EW discovered from the team composed by me, Riccardo Papini, Massimo Banfi, Alessandro Marchini and Claudio Arena. The period was defined better using the ASAS-SN survey data. Magnitude goes from 15.59 to 15.85 V. Epoch: 2458097.3661 HJD Period: 0.374850 d Link […]
