The blinking star

Post by brian livesey »

A "blinking" star has been discovered by astrophysicists in the central part of the galaxy that lies more than 25,000 Lys away. The star, catalogued as VVV-WIT-08, could be the first of a new class of "blinking giant" binary stars consisting of a star100 times the mass of the Sun that is eclipsed every few decades by a stellar companion.
Many stars change their luminosity over time, but its a rarity for a star to become fainter over months then brighten again. The study is published in the Monthly Notices of the Royal Astronomical Society.

Huh? Isn't that what most Mira variables do?

Mira is a pulsating variable, not an eclipsing binary.
