Would it be possible if you would help me with a quick question, (as none of the staff here, or postgraduates can answer this question)? My group are designing a gamma ray telescope to look at nucleosynthesis in Supernovae. We have found a thing called the 'mass cut' (the separation between...

Cheers.

I mean -0.6830

Cheers. Can I confirm that the absolute magnitude is 0.6830?

ah that does make a lot more sense. So the ratio of the L/Lsun = 357.4

L/L_sun = 2022 -25.9=-2.5log\frac{F_{sun}}{F_0}\\ m=-2.5log\frac{F}{F_0}\\ equating \frac{10^{10.36}=F_{sun}}{10^{\frac{m}{-2.5}}=F}\\ \frac{10^{10.36}}{10^{\frac{m}{-2.5}}} = 2022 therefore m=-17.64 Can you please advise me on what I have done wrong here? (I was having problems inserting the...

Homework Statement Two stars are in a circular visual binary system. The orbital period of the binary is 30 years. The distance to the binary is 20 parsecs. The angular radius of the orbit of each star is 1". What are the masses of the two stars? each star works out to be 4.4 solar...

Jees, I never saw that I assumed 1"=1' Cheers
