What makes us think that the star system Cygnus X-1 contains a black hole? A, It emits X rays characteristic of an accretion disk, but the unseen star in the system is too massive to be a neutron star. B. No light is emitted from this star system, so it must contain a black hole. C. The fact that we see strong X-ray emission tells us that the system must contain a black hole. D.Cygnus X-1 is a powerful X-ray burster, so it must contain a black hole.

While working with part of a research team you discover a set of exoplanets in a nearby star system. One of the planets is much closer to its mother star than the other and because of this you are able to determine the average radius of the closer planets orbit to be 37.26 x 10 to the 6 kilometers the Planet complete one orbit every 53.4 days. a) what is the mass of the star in this system?
Solve the following problem: Two stars, named A and B, each with a mass equal to the Sun's mass are in orbit around each other. If the distance between the two stars is 1.0 AU. What is the period of their orbit? Describe each step in solving the problem:
I attempted to answer this question and I'm not sure what I am doing wrong. My formula says A.S. = 206265 (separation/distance from observer) I know to convert to the same units, so I ended up with 80 Million Km being 8 x 10 ^ -6 LY Could you please explain each step especially for the part that I got wrong for both A and B?
You measure a star to have a parallax angle of 0.12 arc-seconds What is the distance to this star in parsecs? 8.33 Hint: d = 1/p What is the parallax angle of a different star that is twice as far away as the star from the previous problems? [answer in arc-seconds without including the unit]
1.) How far, in parsecs, is an object that has a parallax of 1 arc second? How far is it, in light years? 2.) How far in parsecs, is an object that has a parallax of 0.1 arc-seconds? How far is it, in light years?
