Re: Astronomy C

Okay I have more questions! Hehe :D Anyway so say you had a problem like this: Consider the following velocity curve for a binary star system for the questions. Positive velocities are radially away from the observer. The stars in the system are separated by 2.17E10 m and the observer is in the pla...

I need help! This may be late but i'm a little (a lot) confused about this and my competition is on Friday :oops: Here's an example problem: A particular star has a parallax of 37.4 milliarcseconds and a proper motion of 173 milliarcseconds/year. Its peak wavelength is 415 nm, its apparent magnitude...
