Abstract

In this preliminary analysis we discuss on a statistical inversion method applied to themeasured stellar Vrot sin i. Our goal is toobtain the Vrot of the cluster stars which is a key parameterof stellar evolution computations. We estimate rotation impact on the age determination ofcluster stars using the Maeder-Zahn’s theory of stellar rotation in the Cesam2k code.
