Position of GJ 357 b in the radius-versus-mass diagram. Different colours indicate the planetary parameters derived using the different datasets of stellar masses and radii. Continuous lines indicate the estimates based on the Keplerian amplitude and planet-to-star radius ratio by Luque et al. (2019) while dotted lines show the results based on the analysis by Jenkins et al. (2019). A few exoplanets from NASA’s exoplanets archive are overplotted as grey circles. Different planetary models (from Zeng & Sasselov 2013; Zeng et al. 2016) are also shown for comparison.
