Alex1995 said:ok scratch my last answer. i am new and only 16 but i think its like this:
I have seen many posts saying that the stars spin, the spin is provoked by the conservation of angular momentum.
This is a theory though, since we cannot tell for sure if other stars rotate like our sun.
Though Pulsars rotate, the theory on this is: you take a large object with a slight rotation and compress it down, the rotation speed will increase.
We know pulsars rotate and can check their rotational speed by calculating by how rapidly they pulse.
The problem is.. We do not know if Pulsars rotate due to the SuperNova explosion or due to the previous star spinning and then being compressed and its rotational speed increasing... A computer simulation was made, and they sadly... found out that the spin was caused by the Super Nova explosion itself. {Meaning that the previous theory is now canceled out}
so... we still don't really know...
(Sorry for my spelling, language) I am not sure my answer is right but i tried.
Stars rotate due to the conservation of angular momentum. As the star forms from a collapsing cloud of gas and dust, any initial rotation is amplified by the shrinking of the cloud. This rotation continues throughout the star's lifetime, with the outer layers rotating faster than the inner layers.
The rotation of stars is primarily caused by the initial rotation of the gas and dust cloud from which they form. This initial rotation is then amplified by the shrinking of the cloud as it collapses to form a star. Other factors, such as interactions with other stars or planets, can also affect the rotation of stars.
The rotation of stars can affect their appearance in several ways. For example, stars that rotate faster tend to have a more oblate shape, meaning they are flattened at the poles. This can cause them to appear brighter at the equator and dimmer at the poles. Rotation can also affect the strength and distribution of magnetic fields on the surface of stars.
The origins of star rotation can be traced back to the formation of stars from collapsing gas and dust clouds. As these clouds shrink, their rotation is amplified due to the conservation of angular momentum. Other factors, such as interactions with other objects, can also influence the rotation of stars.
The rotation of stars can impact their lifespan in a few ways. For one, faster rotation can cause stars to lose mass more quickly, shortening their lifespan. Additionally, the rotation of stars can affect their internal structure and energy production, which can also impact their lifespan. However, the exact impact of rotation on a star's lifespan is still an area of ongoing research.
