Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.
Stars come in a wide range of sizes, masses and compositions. Our sun is considered a relatively small specimen, especially when compared to something like Betelgeuse which is known as a red supergiant. Red supergiants are stars over nine times the mass of our sun, and all this mass means that when they die they do so with extreme ferocity in an enormous explosion known as a supernova, in particular what is known as a Type-II supernova.
Enjoying Kyoto So Far
Kyoto Sangyo University, Japan
My name is Kiana Davis, and I am a linguistics major studying abroad at Kyoto Sangyo University in Kyoto, Japan. I m less than halfway through my year-long exchange, but I ve already had so many wonderful new experiences here in Japan so far. I have made many new friends with both international students and locals, seen many new places both in and around the city, and have even found enjoyment in some of the more mundane aspects of living in Japan. I can t say everything is picture-perfect here, and my language abilities aren t quite where I want it to be yet, but regardless, I know coming here on exchange is something I ll never forget and never regret.
