Infrared dwarfs: Surface gravity sensitivity in H-band spectra
The age of the center of our galaxy is poorly known. Determining the ages of individual stars in the galactic center usually requires isochrone fitting on a Hertzsprung-Russel diagram, which in turn requires knowledge of the star’s fundamental parameters, such as surface gravity, which is often determined with spectroscopic methods; and metallicity, which affects the shape of the isochrone. This c
