star-binary
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

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)
