Spectroscopic Bolometric Corrections and Empirical Zero-point Constants of \textit{Gaia} Magnitudes, $G$, $G_{\mathrm{BP}}$, and $G_{\mathrm{RP}}$, from \textit{Gaia} XP Spectra

Zeki Eker, Gökhan Yücel

The International Astronomical Union 2015 Resolution B2 (IAU2015GARB2) has resolved the long-standing problem of zero-point constants for the absolute and apparent bolometric magni…
