Spectra of stripped-envelope stars as a unifying sequence – Götberg et al (2018)

Ylva Götberg’s second paper on the spectra of the stripped stars stripped is now accepted, featuring “obese subdwarfs”, “underweight Wolf-Rayet stars” and everything in between, including a demonstration of why astronomers are effectively colorblind, making these stars nearly invisible to us when they have a companion.
