Useful Astrophysical Numbers, Concepts, and Compendia
My own compiled list of numbers:
solar absolute magnitudes in ugrizK are (6.41,5.15,4.67,4.56,4.53,3.32), from Bell et al. 2003.
Astrocalculator - (borrowed directly from Chris Dolan's webpage at Wisconsin) awesome little Java script with all your desired constants at the push of a button, PLUS it's a scientific calculator.
Astroconst - ready to use astronomical constants header files in Fortran, C and Perl.
Astronomica - The AstroWeb Site (Glossary)
Astronomy Unbound - A virtual astronomy text for undergraduate level.
Atomic Elements - clickable periodic table with useful info from American Element.
Cosmos - The SAO Encyclopedia - a unique on-line astro reference by research astronomers.
Cosmological Calculator - input your favorite cosmology flavors of the month and get back physical parameters for a given redshift (from Ned Wright).
Equatorial to Galactic Conversion: here , here , NED
