Old stellar populations .4. Empirical fitting functions for features in the Spectra of G and K stars
Gorgas García, Francisco Javier ; Faber, S. M. ; Burstein, David ; González, J. Jesús ; Courteau, Stéphane ; Prosser, Charles | University Chicago Press | 1993-05Empirical fitting functions are presented that model the behavior of 11 strong atomic and molecular features in the spectra of Galactic G and K stars. The functions express the strength of spectral features as a function of V - K, surface gravit[...]![]()
