Homework Statement
Sirius is a visual binary with an orbital period P = 49.94 yr. Sirius A (the bright
star) has an angular semimajor axis of ~A = 2.4190'", while Sirius B (the fainter
star) has ~B = 5.191". The distance to the Sirius system is 2.64+-0.01 pc. What
are the masses of Sirius A and B? What are the uncertainties in the masses?
Homework Equations
M=m1+m2=(4pie^2 d^3 a^3)/Gp^2
The Attempt at a Solution
my question is for the distance would i just put 2.64 pc or need to do something with the +- .001? and the uncertainties in masses would be .01/100? Also is this question asking for mass of each star or total? Not sure how you can find the individual mass with this data.
