And now my friend Stuart who runs Astronomy Blog has done it one better: he’s created an H-R diagram of media stars. It’s awesome: That’s really funny, and I wish I had thought of it. The ...

The Hertzsprung-Russell (H-R) diagram is simple. It plots two basic properties of stars: their luminosity (intrinsic brightness) and their surface temperature (as revealed by their color).

NGC 6397 contains more than 400,000 stars, which gives us a lot of points. Using the color and magnitude of each star, we can convert to temperature and luminosity and put them on the H-R diagram.

Stars come in different types, and most stars will change types throughout their lifetimes. Stars are often organized using what's known as the Hertzsprung-Russell (H-R) diagram. Stars like Earth ...

The HR diagram plots stars's luminosity versus temperature, and most stars fall along the main sequence, where they live most of their lives. 07/23/2015 | Rating NR ...

IT has been suggested several times1 that the flare activity observed in flash and U V Ceti stars is of a nature similar to that of solar flares. In this communication I shall adhere to this point ...
