Alfirk
Bet
Variable starIts story
Alfirk, beta Cephei, is the prototype of an entire class of variable stars —the 'Beta Cephei' variables— that pulse on hourly scales through contractions of their own atmospheres. She is blue, hot and immense, 685 light-years away: her light set out at the close of the Middle Ages, when Constantinople was still Byzantine. The name comes from the Arabic «al-firq», 'the flock'.
