Top: DSEP model tracks of ﹩{L}_{\star }﹩ vs. ﹩{\rho }_{\star }﹩ for different metallicities, with the parallax-based ﹩{L}_{\star }﹩, transit-based ﹩{\rho }_{\star }﹩, and corresponding errors for Kepler-42 shown as a black point. While the more empirical estimate matches the [Fe/H] = 0 isochrone, Kepler-42 is metal-poor ([Fe/H] = −0.5). Models are restricted to >3 Gyr and [α/Fe] = 0. Bottom: posteriors for ﹩{\rho }_{\star }﹩ from the transit-fit (black), empirical calibration from nearby stars (orange), and DSEP model (teal, matching [Fe/H] = −0.5 on top panel).
