Abstract Aoyama et al. provided scaling relations between hydrogen-line luminosities and the accretion luminosity for planetary-mass objects. These fits should be an improvement over blind extrapolations of stellar relations. The fits go up only to the n = 8 electron energy level, but higher- n Balmer lines have been observed in the near-UV with UVES. We extend the scaling relations to higher- n levels for the Balmer and other series by fitting the fit coefficients ( a , b ) themselves and extrapolating them. Within the assumption of an accretion shock as the source of line emission, these fits should be robust for accreting planetary-mass objects.
