On the (non-)universality of the mixing length parameter.

PINHEIRO F.J.G. and FERNANDES J.

Abstract (from CDS):

The success of the Böhm-Vitense formalism - the so-called mixing length theory - for the treatment of the energy transport in the superadiabatic stellar region in reproducing the properties of the Sun and other stars is well testified by the fact that it is commonly used in almost all stellar evolutionary codes. Yet, several results are pointing out against such an assumption. In this work, we address the universality of the mixing length parameter and search for a possible dependence on several global stellar parameters. While we observe a significant degree of correlation between the mixing length parameter and both the stellar mass and effective temperature. No such indication is found regarding the stellar activity, as stated by previous works.
