Variability Discovered in Star System


By admin - Posted on 30 July 2014

Arizona astronomers have used the MMT's adaptive optics system and the ARIES instrument to discover significant changes in the appearance of the variable binary star system UY Aurigae since 1994. The new spectrum is only the second ever published for one of the stars. The changes in brightness indicate increased interaction between the stars and their circumstellar disks.
