Tc slopes versus age and the mean of the apo- and pericentric distances for the solar twins in our sample. Gray solid lines provide linear fits to the data points.

Rmean versus age for the full sample. Red squares represent the stars with negative Tc slopes, and the stars with positive Tc slopes are marked by blue circles. Gray solid line provides linear fits to the full data points.

[X/Fe] versus Tc at three different galactocentric distances. The [X/Fe] values derived using the Galactic abundance gradients of Galactic Cepheids from Lemasle et al. (2008, 2013). The lines with different colors represent linear fits of the data.
