¶ Accreting planets have been detected through their hydrogen-line emission, specifically Hα. To interpret this, stellar-regime empirical correlations between the Hα luminosity LHα and the accretion luminosity Lacc or accretion rate Mdot have been extrapolated to planetary masses, however without validation. We present a theoretical Lacc-LHα relationship applicable to a ...
