What is the escape velocity (in km/s) from the surface of a 1.1 M. neutron star? From a 3.0 M, neutron star? (Hint: Use the formula for escape velocity, V̟ = 2GM -; make sure to express quantities in units of meters, kilograms, and seconds. Assume a neutron star has a radius of 11 km and assume the mass of the Sun is 1.99 × 1030 kg.) 1.1 M neutron star km/s 3.0 M. neutron star km/s If a neutron star has a radius of 12 km and a temperature of 8.0 x 10° K, how luminous is it? Express your answer in watts and also in solar luminosity units. (Hint: Use the relation . Use 5,800 K for the surface temperature of the Sun. The luminosity of the Sun is 3.83 x 1026 W.) luminosity in watts luminosity in solar luminosity units Lo
