Does anyone know where i can find Right Ascension, Declination, and distance-from-us values for all the nearest stars and brown dwarfs to us, in a database format like CSV or similar file format?

I know wiki has a list at http://en.wikipedia.org/wiki/List_of_nearby_stars, but I'm looking for it in a computer format that I can read in.

I love playing with data. If you have a different site or catalog in mind but need it in .CVS format, I would be happy to take a shot at it. I'd likely ask permission from the site/catalog owner, but that is just more interesting.

The list from Wikipedia copied and pasted straight away into an Excel workbook. Would that work for you? The paste function retained the colors,mixed-cell dimensions and links.

I'm with schlaugh! You should be able to read the data in from that list at wiki.

A couple of years ago I wrote a simple star viewer program using the data from The HYG Database (http://www.astronexus.com/hyg). The full version has around 120,000 stars in it!

I haven't looked at the code in ages - thanks for the reminder... :-)

Yeah, that helps. Thanks for the link.

Thanks for your help everyone, glad to see there are others who share my passion for computer simulations.

I used this page:

http://www.chara.gsu.edu/RECONS/TOP100.posted.htm

This data is accurate as of 2012, more recent than the other link posted (2006).

I removed the excess lines, and then wrote a simple program to convert the data into the form I desired. I used octave (similar to MatLab), but today I'd use python.

The Tycho 2 catalog has the 2539913 brightest stars. This includes the nearest stars, but will be a bit short on the brown dwarfs.

There may be other catalogs at that site with more specific information. For example:
