Radius vs. effective temperature. Background black shading indicates the distributions of the Kepler stars with revised radii based on the Gaia DR2 parallaxes presented in Berger et al. (2018). Red circles, green triangles, and blue diamonds are solar-type stars in our catalog that have been judged as solar-type stars in the Kepler Input Catalog (Kepler Data Release 25 Notes; Thompson et al. 2016). They are classified as main-sequence stars, subgiant/main-sequence binary stars, and main-sequence binary stars, respectively (Berger et al. 2018). The solar value is also plotted for reference (circled dot).
