Animated Hertzsprung-Russell Diagram with 119,614 datapoints
About
Got bored with a lot of the Hertzsprung–Russell diagrams out there, so I made and animated my own using 119,614 data points in a star catalog.
Stars twinkle for two reasons:
- Aesthetics
- Reduces overploting

Notes:
If you're going to play with this:
- Make sure you have FFMPEG installed
- the last line is optimized to work with unix-like systems (Linux/Mac, basically). If you have Windows, replace it with
DEL star_anim*.png
- make sure the second line has the correct working directory under
setwd()
.

I'm told that this star catalog may potentially contain inaccurate information. See comments here.
