Variable star discovered by the astronomical observatory of Capannori and Florence

And' the fruit of a collaboration between the astronomical observatory of Capannori and Florence, dedicated to Margherita Hack, the discovery of a new variable star is a star whose brightness varies over time, which is in the constellation of Vulpecula. The science team compound, Matteo Massimo Maria Santangelo , Massimiliano Mannucci and Nico Montigiani last week when she posted on the bulletin international professional The Astronomer''s Telegram the discovery.

All the data have been taken from the Montigiani and Mannucci through the telescope from 35 cm of the Osservatorio Astronomico Margherita Hack as the statistical analysis of the data, the writing of the publication and the bibliographic research, and sitografiche have been made in the vast majority of Santangelo with software also developed in their own right (with regard to the statistical analysis of the data) by the staff of the Astronomical Observatory of Capannori.

The star had already been catalogued by astronomers in the past with the name USNO A2.0 1125-17013138 but no one had ever noticed that its brightness varied over time, and men who never had given the time period. Thanks to the sophisticated software known as ATSA (Astronomical Time-Series Analysis) and realized by the staff of the Observatory Astrononico of Capannori has been possible to analyze the measurements of brightness taken by the staff of the Osservatorio Astronomico Margherita Hack and determine that the change in the light of this star is statistically significant, and that the period is 0.4179, or exactly double that is 0.8358 days. © Reproduction reserved
