Stars and electromagnetic waves/radiation

Click For Summary
SUMMARY

Stars produce electromagnetic waves through nuclear fusion processes occurring in their cores, where hydrogen is converted into helium, releasing energy in the form of radiation. This energy is emitted as electromagnetic waves across the spectrum, including visible light, radio waves, and more. The discussion highlights the analogy between stars and antennas, emphasizing the role of oscillators and resonance in the emission of these waves. The YouTube lecture referenced provides a detailed explanation of angular momentum and energy collapse, which are critical to understanding the mechanisms behind stellar radiation.

PREREQUISITES
  • Nuclear fusion processes in stars
  • Basic principles of electromagnetic radiation
  • Understanding of oscillators and resonance in electronics

NEXT STEPS
  • Watch the YouTube lecture on stellar energy and electromagnetic radiation starting at 28 minutes
  • Research the process of nuclear fusion in stars, focusing on hydrogen to helium conversion
  • Explore the electromagnetic spectrum and its relevance to stellar emissions
  • Study the principles of antennas and how they relate to electromagnetic wave transmission
USEFUL FOR

Astronomy enthusiasts, physics students, radio electronics hobbyists, and anyone interested in the fundamental processes behind stellar radiation and electromagnetic wave production.

Homework Statement



I am just interested to learn how stars are able to produce electromagnetic waves/radiation (The PROCESS(es)).
I am into 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)

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:
