AI Thread Summary
Stars do rotate due to angular momentum acquired during their protostar phase. Once formed, stars like the Sun continue to exhibit angular momentum, with the Sun's equator completing a rotation approximately every 24.5 days. The gaseous nature of stars allows different latitudinal regions to rotate at varying rates. This phenomenon is a key aspect of stellar dynamics and influences their evolution. Understanding angular momentum is essential for studying star behavior and formation.

Hello,

Do stars rotate? I mean to say that do they rotate in angular momentum? Or there is any other rotation?
 
Astronomy news on Phys.org
Yes, stars rotate due to angular momentum acquired from gravitational collapse during their protostar phase.
 
Hello,

Thanks. I believe pro star is the earlier stage of star formation. What happens when the star if finally formed? Does it have a angular momentum then also?
 
The star we know best, our sun, is "finally formed" and it rotates. According to wikipedia, http://en.wikipedia.org/wiki/Solar_rotation
its equator makes one rotation in about 24 and a half days. Of course, because it is gaseous, different parts, at different latitudes, can rotate at different rates.
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
