After many differnt typs of astronomical measurements, it is now that believed that X-1 is a black hole
a. Find the location of this black hole relative to earth
b. Caculate Schwarzchild radius of the Cygnus X-1 black hole
Help I haven't been able to find the mass of Cygnus X-1. I cannot caculate the schwarzchild radius without this information. I guess I am stumped. Been on the net and totally confused.
Equation for Schwarzchild radius r=2GM/(c squared)
R=radius G=Gravitational Constant M=Mass C= Speed of light
Thanks for posting your question to Brainmass.
All the data you require can be found at this database (an excellent information site):
and specifically for the HDE226868 star:
Right Ascension and ...
The different types of Astronomical measurements are determined.
