Amanda Karakas One of the most important research fields in astrophysics is the study of the origin of the elements. ... Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...

... Be Stars . ... Stellar Winds . ... He had found the first emission line star. ... More emission line stars were found soon, and one had to make subclasses to keep some overview. Cas is a main sequence B-type star, and together with other such stars showing hydrogen emission it forms the class of "Be stars", where the "e" stands for emission. ... Struve further speculated that those stars would be surrounded by a disk, basically thrown off the stellar surface by the rapid rotation. ...

. This artist's illustration depicts a gamma-ray burst illuminating clouds of interstellar gas in its host galaxy. By analyzing a recent gamma-ray burst, astronomers were able to learn about the chemistry of a galaxy 12.7 billion light-years from Earth. They discovered it contains only one-tenth of the heavy elements (metals) found in our solar system. // Gemini Observatory/AURA, artwork by Lynette Cook
