Notes. (a) For comparison, the results from Hellier et al. (2009) that considered free eccentricity were used. (b) Values converted to cgs units multiplying by the Sundensity ρ⊙ = 1.408 cgs. (c) Values converted to cgs units multiplying by the Jupiter density ρJ = 1.33 cgs. (d) Values enclosed in parentheses correspond to the uncertainties of the last digits of the nominal value.
