H-R Diagram of media starsThat's really funny, and I wish I had thought of it. The vertical axis is fame, as denoted by Google results, and the horizontal axis is peer-reviewed papers. I'm actually ...

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).

Need a break? Play the USA TODAY Daily Crossword Puzzle. On the H R Diagram, you can see that stars gather in groups. 90% of all stars are Main Sequence stars.

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.

Left, Russell. Right, ESA/Gaia The early HR diagrams only had data for about 300 stars, but even then it was clear most stars lay along a linear path known as the main sequence.

Just as with stars, there's a main sequence of quasars. Only, unlike the main sequence of the H-R diagram, this one is more like a ‘main wedge’, as you can see. Figure 1 in the paper.

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.
