Is MC22 a Neutron Star or a Black Hole?

[col1973]

Can anyone help please,

MC22 is a very bright source, radiating at L=10^31W. However, no rapid periodic pulsations are apparent in the X-ray flux. It suggested that this emission arises from accretion of material from a star onto either a neutron star or black hole. From these facts can you conclusively exclude neither, one or both of these possibilities? Show how you arrived at your answer.

Any help would be great,

thank you Col.

How do you work out the mass of the object please?

 

[Freshtictac]

Is MC22 real or imaginary object?
How far is it? (Length)

What is it's width?
*10^31?

This may help you if you currently do not know L or W of MC22 whether real or imagined.
