Conservation of angular momentum A spherical star with radius R1 7.96 x 10 km and rotating with angular speed (o 3,92 x 10s rad/s suddenly collapses into a neutron star. The neutron star emits a beam of X-rays directed radially outward that can be seen by an observatory on the earth r 4.55 x 104 km from the star. The X-ray beam sweeps past the earth with a tangential speed v 7.40 x 10 km/s each...

9. (5 Pts.) A star with a radius R, 109 m is rotating with initial angular velocity w 108 rad/s. The star collapses in on itself until it becomes a neutron star with the same mass, and a final radius Ry 10t m. Modeling the star as a uniform solid sphere, what is the final angular velocity of the star? (Hint: angular momentum is conserved)

10*) The Sun has approximate radius 7×108 m, and rotates around
its axis once every 27 days. a) Find its angular velocity in rad/s,
and (assuming it is a uniform sphere) write a formula for its
angular momentum expressing it in terms of its mass M (you do not
need to substitute a value for M). b) Suppose the Sun were to
collapse to a neutron star, which is a much denser state, without
losing any mass and without being...

An isolated star with the radius of the Sun (6.95 × 108 m) rotates on an axis through its centre once every 2.16 × 106 s. It collapses under gravity to form a much denser star with the radius of the Earth (6.38 × 106 m). For the purposes of this question, you may assume that no matter is lost from the star during its collapse. You may also treat the star as a homogeneous sphere before and after the...

Formation of a Neutron Star A star rotates with a period of 29 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radlus of 1.5 x 104 km, collapses into...
