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).

Now known as Hertzsprung-Russell diagrams, or HR diagrams, they plot the color or spectral class of a star versus its absolute magnitude.

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 ...

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 ...
