GSC 04463-01015: EW System discovered

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 […]

UCAC4 760-020518: EB System discovery

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 […]

UCAC4 662-020393 – EW system discovered

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 […]

UCAC4 552-028220 – EA System discovery

Poker! Another variable star has been discovered by the team composed by me, Massimo Banfi and Riccardo Papini (WBRO – K49) and Alessandro Marchini (Astronomical Observatory of University of Siena). This is the UCAC4 552-028220 located in Gemini, a very nice EA semi-detached system that seems almost an EB system. We covered almost all phase […]

GSC 02872-01923 – EW system discovery

Another EW system has been discovered thanks to a strong collaboration with Alessandro Marchini, Riccardo Papini, Massimo Banfi, Claudio Arena and Giorgio Bianciardi. This system, located in Perseus, is a very nice EW system with a clear O’Connel effect. It was not possible to cover all the phase, but the period is well fixed. We […]

GSC 04051-01319 – EW system discovery

And, again, we are back. This is a nice EW system located in Cassiopeia. The discovery is from the last mid august thanks to the telescope of Osservatorio Astronomico of University of Siena by Alessandro Marchini. Me, Riccardo Papini and Massimo Banfi observed the system again with the WBRO (K49) during other two nights, few […]

UCAC4 590-041015 – EA System discovery

After five months, we back to discover variable stars. And this is the first (real, not imported) post in my new website. The new variable star is the UCAC4 590-041015 in Gemini. We – with Alessandro Marchini and Riccardo Papini – discovered this system on 16 january 2016. But it was really difficult to complete the […]
