Neutrinos in Stellar Astrophysics

Understand

The physics of the mysterious and stealthy neutrino is at the heart of many phenomena in the cosmos.

• These particles interact with matter and with each other through the aptly named weak interaction.
• At typical astrophysical energies the weak interaction is some twenty orders of magnitude weaker than the electromagnetic interaction.
• However, in the early universe and in collapsing stars neutrinos can more than make up for their feeble interaction strength with huge numbers.
