A new EA system, UniSi_V117 (UCAC4 762-005092 in Cassiopeia) has been discovered from telescope of University of Siena with the help of members of the SSV-UAI: Fabio Salvaggio, Alessandro Marchini, Riccardo papini, Massimo banfi, Lorenzo barbieri, Claudio Arena, Nello Ruocco and Giorgio Bianciardi. It was difficult to calculate the correct period. ASAS-SN needed to be […]
