Apr 4 @ 15:30 – 16:30
We present new spectral diagnostics available from HR15n spectra of stars in the gamma2 Vel cluster, useful for classification and determination of fundamental stellar parameters. We define several spectroscopic indices, sampling the amplitude of TiO bands, the H-alpha line core and wings, and temperature- and gravity-sensitive sets of lines, each useful as a temperature or gravity indicator over a limited
