AI Thread Summary
Stars do not possess Van Allen radiation belts like Earth, as they lack a magnetic field capable of trapping charged particles in the same manner. The solar wind from the sun contributes to the presence of charged particles in Earth's magnetic field, but this does not imply that stars have similar structures. While stars may have magnetic fields, they differ significantly from Earth's magnetic field. The discussion highlights the dynamic nature of the sun and its emissions, but concludes that the concept of Van Allen belts is not applicable to stars. Overall, the existence of magnetic fields around stars does not equate to the presence of Van Allen radiation.

Hello,

I have a question: Do stars have Van Allen Radiation?

Thanks
 
Astronomy news on Phys.org
The solar wind emitted by the sun is thought to be the source of the charged particles which become trapped in Earth's magnetic field.

Due to the dynamic nature of the sun, there are all sorts of particles and ionized matter being thrown off the surface of the sun.

If you could show that a star has a magnetic field surrounding it like the earth’s, then you could say that it would trap particles the same way the Van Allen belt does. As far as I know, stars do not have such a magnetic field.

Actually it flipped already about two weeks ago.

I don't mean to say that is has a Van Allen belt.
But stars may have magnetic fields. Of course, they may not be "like the eart's" in some respects.

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
