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 analysis without other observations. So, we asked help to the friends of SSV-UAI (Variable Star section – Unione Astrofili Italiani): Luca Rizzuti, Claudio Lopresti, Massimo Banfi, Lorenzo Barbieri, Giorgio Bianciardi, coordinated by Claudio Arena accomplished the mission!

We also used the ASAS-SN survey data.

Magnitude goes from 15.53 to 16.30 V, with a secondary minima at 15.71 V.

Epoch: 2457404.4140 HJD
Period: 4.903283 d
