Evolutionary tracks in a log T_eff − log g diagram. The colour code describes ν_max obtained from the scaling relation. The black line shows the location at which ν_max is equal to the Nyquist frequency of LC data. The red and blue lines show the locations of the birthline according to Palla & Stahler (1990) and Behrend & Maeder (2001), respectively. The black crossed object shows the spectroscopic observations for EPIC 205375290.
