An object that eats (absorbs) all energy that happens to come across it. Mmmm tasty.

Planck's Radiation Law.
Also, do we need to know things like Planck's constant or Planck's equation? Or is that out of the scope of RFTS? Because right now, I use Wien's law for calculations and I only have Planck's law as the statement that the curve of emission in a blackbody of a given temperature is always higher than the curve of a blackbody of a lower temperature.

lol ure answer correct
2.
correct
3.
correct
Personally, I don't think Planck's Law's formula should or will be used as A. its kinda complicated and B. im not even sure if were supposed to do calculations with stuff like Wien's Law or Stefan-Boltzmann's Law (those are pretty easy so ig they r ok). But like the definition of Planck's law I feel is within the scope of the event. Although one could argue that no radiation laws should be allowed cuz they arent really in the rules, they come up all the time so ¯\_(ツ)_/¯.
Your turn!
Thanks! The rules mention "relationship between stellar temperature, radius, and luminosity", which is Stefan's Law. Wien's Law & Planck's Law are not mentioned, but I bet they are in previous years' rules because they show up on a lot of practice tests. They're also in Scioly's Wiki for RFTS.
Anyways...
Stellar Evolution
1. Why do low-mass stars live the longest?
2. What is the "turn-off point"?
3. What is name for the class of evolved, massive stars that have completely lost their outer hydrogen and are usually type O?
