Abstract

In this paper we present the latest results in our long-term program to understand how differential rotation depends on fundamental stellar parameters such as spectral type, mass and radius. In this paper we focus on early G dwarf spectral types by presenting our latest surface brightness image and differential rotation measurement for the GOV dwarf HD 171488 (age = 30 to 50 Myr, period = 1.33 d) and compare with the differential rotation measurements obtained using the same techniques for LQ Lup (G2V, 25Myr, p=0.31 d) and R58 (G2V, 35Myr, p=0.57 d).
