Where are the accreting planets? Brightness predictions and prospects for detections by Roman

Recently, theoretical scaling relationships have been obtained between the luminosity in accretion- generated hydrogen transitions, including Paschen beta (1.282 um), and the total accretion luminosity. We have also developed an improved framework for calculating line luminosities from the same non- equilibrium radiation-hydrodynamical models but combined with a more realistic, multidimensional accretion geometry. We apply both the scalings and the updated predictions to statistical studies of planet formation to assess how Roman can best catch planets as they are forming.
