Caption: Figure 4.
Top: mass vs. core mass fraction (CMF). Bottom: mass vs. planet density error as a function of radial aspect ratio (color bars) from tidal distortion. We show the measured mass of GJ 367 b (0.503 ± 0.078 M⊕) as the gray shaded region. We adopt the Fe–pv–en (iron core surrounded by perovskite-enstatite mantle) composition in the right panel of Figure 3.
