Finding the mass of the smaller star in a binary system you'd use the m1 + m2 thing, however, it says one star is 4 times the other so I assumed 5M = answer and divided the answer of m1 + m2 by 5.

yeah that's exactly what i did. seeing as one star was four times the mass of the other, i just put the original equation down and let m2 = 4m1, therefore

m1 + m2 = m1 + 4m1
= 5m1

and divide the answer by 5.

im glad i got something right

Hmm... My teacher almost promised me there'd be a question on the life, evolution and/or death of stars! Strange indeed!

Astrophysics was a bit of a doosie! I found that some questions were asked in a rather awkward and unusual manner - although some was pretty straight forward.

i thought astro was better than the rest of the paper. Everyone in my class found the test hard. It was nothing close 2 past papers.

Bring on economics bitch
