Angular momentum is a measure of the rotational motion of an object. It is the product of an object's moment of inertia and its angular velocity.
The rotation of a star directly affects its angular momentum. As a star rotates, its angular velocity increases, resulting in an increase in its angular momentum.
Angular momentum is conserved in stars through the conservation of angular velocity. As a star contracts, its moment of inertia decreases, causing its angular velocity to increase and maintain the same angular momentum.
The distribution of mass in a star can greatly affect its angular momentum. A star with most of its mass concentrated towards the center will have a smaller moment of inertia and a higher angular velocity, resulting in a larger angular momentum.
Yes, the angular momentum of a star can change over time. Processes such as mass loss, collisions with other objects, and changes in the distribution of mass within the star can all alter its angular momentum.
