I Database of binary star data info within 10 PC of Earth

[Sciencemaster]

TL;DR Summary

I'm looking for a database of binary stars within 10 PC of Earth containing info such as the eccentricity of orbits around one another that's somewhat easy to use.

I'm looking for a database of binary stars within 10 PC of Earth, including information such as eccentricity of orbits, their distance from one another, etc. I'm hoping to find a list with this information, or just a collection of pages with this information. I've tried Simbad but I can't find information on Binary Star Orbits. My question is, is there a publicly available database with this information that's somewhat easy to use to someone without much experience with such databases?

Here's one I found via Google:

https://heasarc.gsfc.nasa.gov/W3Browse/star-catalog/cabscat.html

I imagine a query would be needed to find those systems that close to Earth ala 10 pc.

At the bottom of the page they mention fields x-coords, y-coords, z-coords which could be used via the pythagorean theorem to decide if the system is within your 10pc radius.

and this page seems to allow queries by distance:

then again maybe not. It seemes to index journal articles.

I suspect you will need to do this in two steps - find the systems, and then look up their parameters.

I also suspect you will need to decide what a binary system is/what a star is - i.e. what to do with brown dwarfs. You may or may not be able to get a sharp definition. I would be inclined to consider lithium as the dividing line, but I don't know if all my candidates would have good measurements,

That's a fair point. I have created a list of the binary stars I need information on (I am including orbiting brown dwarfs for the time being, and I can always just ignore them later on), but I'm having trouble finding information on their oribits, as the databases I have tried so far just give me information on the stars themselves--such as brightness and declination--whereas I need to know information about how they orbit around one another. It doesn't help that I'm inexperienced in the use of databases, so I'm not exactly sure how to look for what I need, either.

I would suggest going thru the tutorials on the ESA's Gaia site to gain some experience on the database queries. They are very good, and they also have a database of non-single stars. I haven't gone thru this database, but they may have the orbital parameters, or links to the publications that do.

Thank you very much! That's a good idea, I'll try that!
