Does anyone know if HIP or Tycho databases include the age of stars?
I need to correlate age to mark stars.

Nothing urgent, just a side project.
A matter of curiosity I would like to satisfy.

Sorry, but no, they don't.

That information might be available from the Simbad database at http://simbad.u-strasbg.fr/simbad/

Its response usually, but not always, includes information from many different catalogs when you query it. In addition to displaying Web pages for specific objects, Simbad's information can be retrieved in textual format using scripts. See http://simbad.u-strasbg.fr/simbad/sim-fscript

They don't as selden said, but remember that the most massive stars on the main sequence (200 solar masses) live for only 3 million years.

At least according to mainstream star model, which is still unproven, despite decades of observations
