Good evening, does anyone know if there is a particular stars catalog that is used by professional astronomers and if so is it accessible to the general public?
There are hundreds of star catalogs for different purposes. But you can get a long way with two:
- the Yale Bright Star Catalog, for the brightest stars
- GAIA Early Data Release 3, for the faint ones
All of our catalogs are public, but it will take you some work to find them and figure out the formats.
I imagine that among all these catalogs there are some which have more precise measurements of the distance of the stars for example

For distances, as Jonathan said above, Gaia EDR3 is the place to go (the full release will be later this year).
