Graduate Subtracting the proper motion resulting from movement of the Sun
Hello, I have been trying to compute the velocity of the star with respect to its local medium from the proper motion measurements. Sure, you can calculate the corresponding velocities by v = 4.74*(proper motion)*distance (in suitable units), but this resulting velocity is now with respect to...- rawen

Python How can I properly handle exceptions in my Python program?
Hello, dear PFers. I'm currently beginning to learn Python and I got stuck at one exercise. Homework Statement Basically, I'm supposed to create a simple program that will calculate the position of an object according to the formula y(t) = v0*t - 0.5*g*t**2. Parameters v0 and t are supposed...- rawen
