http://www.exoplanet.eu/catalog-all.php?&mode=0&more=yes". On one of the this it has for the for each exoplanet, in the list it gives the information about the parent star's properties especially its phototemetry. Specifically it lists star's the V-order, I-order, H-order, J-order, and K-order magnitude; however, it does not list the star's absolute magnitude, or luminosity. Is their a way to calculate the absolute or apparent magnitude of the parent star from its photometric magnitudes? If so do how?
