Hi, I was trying to find large star databases to work with, but found that most of the databases I could find did not come close to what I was looking for. Is it possible the data I'm looking for just doesn't exist yet? The data I'm looking for should preferably contain all kinds of stars and be mostly based on the closest stars since that data would probably be the most accurate and complete. But after searching for a while, all the databases I could find were too small (I was hoping for 50000+) or were missing variables that are important to me (mass, density, whether it is part of a binary/trinary system, spectral type, position, space velocity) and the 'would be nice' variables (age, total redshift, lifetime phase, error bars) or I couldn't actually download them. I'm starting to suspect such databases don't exist or aren't placed online, possibly because mass and density might not be too easy to calculate. But I was hoping that someone here might be able to point me to databases I missed.
