star-binary

Post #1by Daly » 06.08.2020, 00:33

Hi, I'm from Chile, I made this catalog with more than 700 binary stars and I would like to share it. You have to delete nearstars because I combine them. I'm sorry, well if someone wants to see, modify or review it

Hi, what source(s) did you use for all the binary orbits?

I got it from https://es.wikipedia.org/wiki/Estrella_binaria_de_contacto
calculate with

r1=(m2*d)/(m1+m2) d=r1+r2
r2=(m1*d)/(m1+m2)

T**2=k*(r1+r2)**3/(m1+m2)

h2=max close up
h1=min close up

r1=((h1+h2)/2)*m2/(m1+m2)

r2=((h1+h2)/2)*m1/(m1+m2)

e=(h2-h1)/(h2+h1)
