For example, the ultraviolet light comes from the youngest and most massive stars, while the optical and near - infrared continuum light is emitted mostly from more evolved stars. (keckobservatory.org)
The spectra indicate a system of evolved stars with nearly equal masses (q = 1.02), where one component shows significant line profile variations while the profiles of the slightly more massive component are constant. (iastro.pt)
Cosmic dust is made in evolved stars. (erccomics.com)
