Calculate the Schwarzschild radius of a 109 solar mass black hole. How does your answer compare with the size of our solar system (given by the diameter of Pluto’s orbit)? 2.9 × 109 km = 20 A

It is said that at the center of every galaxy is a supermassive black hole (the picture below shows a picture towards the center of the Milky Way from the Keck Observatory). By observing the orbits of nearby stars, you can get a crude estimate of the mass of this black hole by assuming the stars have a circular orbit. Consider the star SO-2, which has an orbital period of 16.3 years. Its average distance from the black hole is...

3. In this problem, we are going to examine the supermassive black hole in the center of our galaxy, Sagittarius A.. (a) (15 points) We can calculate its mass using the orbits of stars gravitationally bound to it in the same way that you can use the Earth's orbit to calculate the mass of the Sun). The orbit of a star, S2, has been fully mapped out. Its period is 15.24 yr and semi-major axis length is 980 AU. Using...

The Schwarzschild radius, or event horizon, of a black hole is the distance from a black hole at which the escape velocity is the speed of light. Calculate the Schwarzschild radius of a black hole with the mass of Mount Rushmore (reminder: Mt. Rushmore has a mass of about 3 x 1013 grams).

(in a sense the "sphere of influence") of a black hole can be defined by the distance from the center at which the orbital speed of a star due to the black hole alone (i.e. neglecting...

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
