Gas and dust masses for the born-again ejecta in A30 are estimated to be $M_\mathrm{gas}=(4. 41^{+0. 55}_{-0. 14})\times10^{-3}$ M$_\odot$ and $M_\mathrm{dust}=(3. 20^{+3. 21}_{-2. 06})\times10^{-3}$ M$_\odot$, which can be used to estimate a total ejected mass and mass-loss rate for the born-again event of $(7. 61^{+3. 76}_{-2. 20})\times10^{-3}$ M$_{\odot}$ and $\dot{M}=[5-60]\times10^{-5}$ M$_{\odot}$ yr$^{-1}$, respectively.

Using spectroscopic radial velocities with the APOGEE instrument and Gaia distance estimates, we demonstrate that Kepler-503b, currently considered a validated Kepler planet, is in fact a brown-dwarf/low-mass star in a nearly circular 7. 2-day orbit around a subgiant star.
