Notes.

1. For a homogeneous analysis we used quadratic limb-darkening coefficients derived using the EXOFAST calculator https://astroutils.astronomy.osu.edu/exofast/limbdark.shtml (Eastman et al. 2013) in the J-band.

2. $K_{pl} = \frac{2 π a}{P} \frac{\sin i}{\sqrt{1 - e^{2}}} = (^{\frac{2 π G}{P})_{3}^{1}} \frac{{(M_{⋆} + M_{pl})}^{_{3}^{1}} \sin i}{\sqrt{1 - e^{2}}} .$ ${{\rm{K}}_{{\rm{pl}}}} = {{2\pi a} \over P}{{\sin i} \over {\sqrt {1 - {e^2}} }} = {({{2\pi G} \over P})^{_3^1}}{{{{({M_ \star } + {M_{{\rm{pl}}}})}^{_3^1}}\sin i} \over {\sqrt {1 - {e^2}} }}.$

3. $K_{⋆} = (^{\frac{2 π G}{P})_{3}^{1}} \frac{M_{pl *} \sin i}{M_{⋆}^{2 / 3} \sqrt{1 - e^{2}}} .$ ${{\rm{K}}_ \star } = {({{2\pi G} \over P})^{_3^1}}{{{M_{{\rm{pl}}*}}\sin i} \over {M_ \star ^{2/3}\sqrt {1 - {e^2}} }}.$

4. $T_{eq} = T_{⋆} {(\frac{R_{⋆}}{2 a})}^{1 / 2} (^{1 - A) 1 / 4}$ ${T_{{\rm{eq}}}} = {{\rm{T}}_ \star }{\left( {{{{{\rm{R}}_ \star }} \over {2a}}} \right)^{1/2}}{(1 - A)^{1/4}}$ , where R_⋆ is the stellar radius, a is the semi-major axis, A is the geometric albedo, we assumed an albedo of 0.2 (Crossfield & Kreidberg 2017).
