Bayesian calibration of the mixing length parameter ${\alpha }_{ML}$ and of the helium-to-metal enrichment ratio $\Delta Y/\Delta Z$ with open clusters: the Hyades test-bed

E. Tognelli, M. Dell'Omodarme, G. Valle +2

We tested the capability of a Bayesian procedure to calibrate both the helium abundance and the mixing length parameter (${\alpha }_{ML}$), using precise photometric data for main-sequence…
