UCAC4 410-066217 – EW System discovery

A new EW system in Ophiuchus has been discovered. We saw it, at first time, in may. But we finisched the work just last week. The discovery is made with my Brothers-in-star Alessandro Marchini e Riccardo Papini and the collaboration with friends Mauro Bachini and Giacomo Succi. We also used CRTS data to improve period […]

UCAC4 641-065317 – EW System discovery

A new EW system in Lyra has been discovered, the UCAC4 641-065317. Thanks to the telescope of Astronomical Observatory of Università di Siena and the collaboration of Alessandro Marchini, Riccardo Papini and Davide Agnetti. Over one month was needed to find the correct lightcurve due a period almost equal to 12 hours. Magnitude variation from […]

Scoperta del sistema EW UCAC4 641-065317

E si torna nella Lyra, per la scoperta del sistema EW UCAC4 641-065317, effettuata sempre grazie all’ausilio del telescopio dell’Osservatorio Astronomico dell’Università di Siena e la collaborazione di Alessandro Marchini, Riccardo Papini e Davide Agnetti. La scoperta ha richiesto oltre un mese per il periodo, praticamente prossimo alle 12 ore, che ci ha obbligato ad attendere […]
