High Mass Binary Stars

Science Daily’s article titled, “Astronomers perform largest-ever survey of high-mass binary star systems” explains how two binary stars can join together to form one high mass star that spins at great speeds. We only know of several binaries that are confined to the Milky Way. Astronomers in Brazil have identified 82 high-mass binaries in the Tarantula Nebula. According to the article, high mass stars are important to our universe because they produce more heavy metals and evolve more rapidly; ending their lives as supernovae. Their matter gets recycled to form a population of new stars.

I think this article is directly related to our conceptual objective, because it talks about the mass of binary stars; which is one of the properties of stars. In my notes, I wrote down that the greater the mass of a star equates to more energy it gives off. In our Lecture Tutorial book, we learned that low mass stars live longer by answering questions on the relationship between the mass of a star and the approximate main sequence lifetime of the star in Star Formations and Lifetimes on pages 119 and 120.

This conceptual objective about star properties was cool to learn about because we got to look at impressive pictures of stars in outer space instead of what we see at night when we look up.
