[334] Algol Binary — An illustration by Don Dixon depicting the Algol binary star system, demonstrating the process of Roche lobe overflow and active mass transfer. A cooler, orange-hued subgiant star is shown losing outer layers of gas to a more massive, blue-white main sequence companion through a concentrated stream. The captured material forms an uneven accretion disk around the primary star, while magnetic activity is indicated by darkened starspots on the donor star's surface. This digital illustration was created in 2004 for use in astrophysical journals and educational textbooks to explain the Algol paradox. interior Sky and Telescope - painting by Don Dixon
