Alpha Flying Fish

Alpha Flying Fish ( α Volantis , α Vol ) is a double star ^[10] in the constellation Flying Fish . The apparent magnitude is +4.00, which is enough for observation with the naked eye. Based on the measurement of the annual parallax , an estimate of the distance from the Sun equal to 125 light years was obtained. As of 2010, the two components of the star system were separated by an angular distance of 0.0318 arc seconds at a position angle of 286.9 °. The magnitude difference of the two components is 0.1. ^[11] Perhaps he is a representative of the Sirius supercluster. ^[four]

The main component is an Am star , the spectral class is kA3hA5mA5 V. ^[5] This notation shows that the star has a weak K line of ionized calcium as in class A3 stars, and hydrogen and metal lines like in a class A5 star. ^[12] Estimated age is 427 million years. ^[8] In 1992, it was discovered that the radiation of the star has an infrared excess , which indicates the presence of a circumstellar disk from dust. ^[13] However, subsequent observations have not confirmed the presence of the disc. ^[14]
