Precise Age for the Binary HD 21278 in the Young α Persei Cluster

Precise Age for the Binary HD 21278 in the Young α Persei Cluster

We present a study of the double-lined spectroscopic binary HD 21278 that contains one of the brightest main-sequence stars in the young α Persei open cluster. We analyzed new spectra and reanalyzed archived spectra to measure precise new radial velocity curves for the binary. We also obtained inter...
