PhysicsHigh | how a star's colour tells us its temperature @PhysicsHigh | Uploaded 3 years ago | Updated 11 hours ago
The colour of a glowing object is related to temperature but despite this, astronomers do not use colour directly to determine a star's surface temperature.
After reviewing blackbody radiation, this video discusses why this is and also reviews the two ways astronomers determine a star's temperature.

I refer to the paper by Ren Heller and Jan-Vincent Harre. You can find their paper here - https://arxiv.org/abs/2101.06254

Many thanks to Prof Geraint Lewis and Jan-Vincent Harre for their valuable feedback
