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...

(25 points) A star known as S2 is in orbit around a massive, dark object thought to be a black hole at the center of the Milky Way Galaxy. Based on the spectral type of the star, S2's mass is about 15Mo. The period of the orbit is about 15 years, the eccentricity of the orbit is about 0.9, and the semimajor axis of the orbit is about 1000 AU. Remember that IAU = 1.5 × 1013 cm. In solar...

5) A star (no matter what its mass) spends most of its life Select one: a. as a protostar. b. as a main-sequence star. c. as a planetary nebula. d. as a red giant or supergiant. 6) What is the ultimate fate of an isolated white dwarf? Select one: a. It will cool down and become a cold black dwarf. b. As gravity overwhelms the electron degeneracy pressure, it will explode as a nova. c. As gravity overwhelms the electron...

Now M is the sum of the two masses in units of the solar mass .e. the mass of our Sun), while a is still in AU and P in years. An important application of Newton's generalization of Kepler's third law is being able to dete mine mass of a central body based on the motion of a satellite around that body. If the satellite is much less massive than the body it's orbiting, then M is essentially equal to...

D. Since the proton is moving while feeling a force, work is done on the proton: Won P = Felec Mlax Icoso, where lax is the magnitude of the proton's displacement and is the angle between the direction of that displacement straight to the left in this case) and the direction of the force on the proton. While the proton is approaching the nucleus the work done on it is positive, negative, zero). Important: our attention is now focused on...
