Solar salad, anyone?
Tempe AZ (SPX) Aug 20, 2014
An Arizona State University alumna has devised the largest catalog ever produced for stellar compositions. Called the Hypatia Catalog, after one of the first female astronomers who lived ~350 AD in Alexandria, the work is critical to understanding the properties of stars, how they form, and possible connections with orbiting planets. And what she found from her work is that the compositions of nearby stars aren't as uniform as once thought. Since it is not possible to physically sample a star to d ... read more
