Top panel: ΔΩ_phot vs. stellar age. The empty circles indicate the median ΔΩ_phot values measured at different ages (note that the members of ηCha have been grouped with the members of TWA). The black continuous line connects the median ΔΩ_phot values and the dotted line marks the present solar shear for comparison. Bottom panel: the same plot restricted to stars with mass between 0.9 and 1.1 M_⊙. The gray crosses mark the rotational shear for the Sun at different ages, as predicted by Küker & Stix (2001).
