A first for Malta - Discovery of a new eclipsing variable star in the constellation Perseus

I am pleased to announce the publication of the first discovery of an eclipsing binary star system from Malta in the peer-reviewed Open European Journal of Variable Stars. 

The discovery of this binary star system was made by Stephen M Brincat. Stephen, Winston Grech and myself have then carried out photometric studies on this star system to update its orbital details by observing it over a period of two whole years. This research has allowed us to derive other characteristics of this eclipsing binary star system.  Below is a link to the full scientific version of this announcement.

Published announcement:

Brincat, S. M., Galdies, C., Grech, W. (2019) A new binary star system of EA type in Perseus: UCAC4 735-019611. Open European Journal on Variable stars. January 2019. ISSN 1801-5964. 7pp

Discovery of a new binary star system (UCAC4 735-019611 = USNO-B1.0 1469-0068570 = 2MASS J01561032+5657563) in the Perseus constellation is presented. The shape of the light curve and its characteristics (period of 2.12701 ± 0.00001d, amplitude of V=0.55 mag, initial minimum period epoch HJD 2457363.37784) indicates that the new variable star is an eclipsing binary of Algol (EA) type. We registered this variable star in the International Variable Star Index (VSX) and its AAVSO UID is 000-BLW-283.
