Period-luminosity relations of oscillatory convective modes with mixing length parameters of 1.9 (dashed lines) and 1.2 (solid lines), for stars with 1 M_⊙ (blue), 1.3 M_⊙ (red), and 2.0 M_⊙ (green). All models are from Saio et al. (2015); they were computed for metal abundance Z = 0.008. The small gray circles are presumptive planets around giant stars gathered from the literature, the yellow and blue circles are the planets found in the Lick survey, the dark red circles are stars that show RV variability that is probably produced by stellar activity, and the yellow and blue stars are the new planets and planet candidates presented in this paper.
