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...

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...

7. Antares is a star in Scorpius constellation. Its radius is 3.0AU and its mas is about 12 times the mass of the sun. Antares orbital speed is 20.7 km/sec. Eventually after a couple million years Antares will be converted to a neutron star. Its radius will be 4.3*10-5 AU. Find its orbital speed after it becomes neutron star? Find your answer by rpm. Moment of inertia of sphere is = 2/5 MR2 - 8. A rotor disk in...

Imagine a hypothetical star of radius R, whose mass density ρ is constant throughout the star. The star is composed of a classical ideal gas of ionized hydrogen, so there are free protons and free electrons flying around providing the pressure support. The star is in hydrostatic equilibrium (a) What is the pressure as a function of radius in the star, P(r)? As a boundary condition, the pressure at the surface should be zero, P(R) 0 (b) What is the...
