pp chain reaction in stars⤴

from @ fizzics

Twinkle, twinkle little star, How I wonder what you are. Giant thermonuclear reaction; Held by gravitational attraction. Twinkle, twinkle little star, You look so small ’cause you’re so far. As you burn through constant fusion, Your twinkle’s just an optical illusion. That happens when your light gets near; distorted by our atmosphere. Twinkle, twinkle little ... Read more

AH: the Hertzsprung Russell diagram⤴

Our Sun is a typical yellow star, so its emission would be represented by the middle star in this image. image courtesy of kstars, kde.org – colour is exaggerated The colour of a star also tells us something about the expected behaviour of a star, it’s lifetime, and destiny. This is achieved by plotting stars ... Read more
