Stars and electromagnetic waves/radiation

  • #1

Homework Statement



I am just interested to learn how stars are able to produce electromagnetic waves/radiation (The PROCESS(es)).
I am in to radio electronics , but have wondered how electromagnetic waves can be produced by stars. I guess 'why' is radiation given off, how is the energy converted from the original form of energy into electromagnetic radiation?. This fascinates me


Homework Equations



-Probably not important. I just want to understand the concept.

The Attempt at a Solution



I know that a radio that transmits waves from an antenna in the form of electromagnetic waves, and this requires elements such as an oscillator, capacitor, inductor, resonance etc etc. I guess the star is like an antenna transmitting?, But how?? (what is the exact process for this , what must occur reaction wise for this to occur)

Start at about 28 minutes in ...

The first part of the lecture is on Angular momentum, but at about 28:00 he starts talking about stars and energy and collapse. It might begin to give you an idea about where the engine for em radiation comes from.

Thankyou very much LowlyPion :smile:
That is a very good video. That professor explains very well the concepts.
It makes me want to learn even more about it :smile:
