Answer 1

Answer #1

Answer: 0.2 solar luminosities

The formula to identify the luminosity of a star is,

L / L0 = (R/R0)2(T/T0)4

Here, R0 = 6.96*105 km

T0 = 5800 K

L / L0 = (10 km/6.96*105 km)2(1,000,000 K/5800 K)4

= 0.2 solar luminosities

Two identical probes are sent along the same path toward a neutron star. A neutron star is very dense, packing as much as 2 solar masses into a sphere with a radius on the order of 10 km. At the moment shown, the two probes are 57.5 km and 118 km away from the center of the neutron star, respectively. Find the distance between the center of mass of the two probe system and its center of gravity. Number km...

To first approximation, a neutron star may be treated as a non-interacting gas of neutrons (spin-1/2 fermions). ( a) Find an expression for the degeneracy (zero point) energy of the star as a function its mass M and radius R. (Don’t worry that our calculation for degenerate Fermi systems was done for particles in a cubical box, the same results apply to a sphere of the same volume.) (b) Write down an expression for the gravitational potential energy of the...

Astronomers use evidence of rapid rotation as identification of a neutron star. As you might imagine, if the mass of a star becomes condensed (collapsed star will have a smaller radius), its density increases. Imagine a star with a core the size of our sun 7 hundred thousand km and a mass 2x that our our sun. This star completes one revolution in 10 days. Should this star undergo gravitational collapse to a radius of 10 km, what will the...

Betelgeuse, a bright red star in the constellation Orion, has a luminosity that is 100,000 times that of the Sun However, the surface temperature of Betelgeuse is only 3000 K. Assuming that the emissivity of stars is 1, find the radius of Betelgeuse.

A neutron star is a star that remains after a supernova, having a large enough density that the it is comprised of mostly neutrons and few protons. A pulsar is a neutron star that spins, radiating electromagnetic energy. We detect this energy as radio waves, noticing that they pulse at a rate of 1 kHz (1000 Hz). Let's assume that this rate corresponds to the rotations per second of the star (1000 rotations per second). Any solid sphere has a...

[4] For the previous planet and star (with a luminosity = 0.041 solar luminosity), assuming a circular orbit, what would be the distance from the star such that the planet's surface temperature is 280 K (no atmosphere or greenhouse effect to worry about)? What are the orbital period and circular velocity of the planet? What is the circular velocity of the star (in m/s) that would be measured with the Doppler shift?
