Modified Hertzsprung-Russell diagram (Δν vs. T_eff) showing the Sun and the 297 stars for which the rotation period, P_rot, was successfully measured and a large frequency spacing is available from Chaplin et al. (2014). Hot stars are shown in red and defined as having T_eff> 6250. Dwarfs (T_eff ≤ 6250 and log g> 4.0) are shown in blue, and subgiants (T_eff ≤ 6250 and log g ≤ 4.0) in green. Effective temperatures are taken from Pinsonneault et al. (2012). The stars for which only the effective temperatures from Huber et al. (2014) are available are plotted in grey. Evolution tracks, computed with the code ASTEC (Christensen-Dalsgaard 2008), are shown for a range of masses at solar composition (Z_⊙ = 0.0246).
