Orbital eccentricities of all the transiting giant planets (0.25M_J < M < 13M_J) plotted with respect to their semimajor axis (a) in AU. The data sets are taken from the TEPcat database (https://www.astro.keele.ac.uk/jkt/tepcat/), and planets whose eccentricities are known to a precision better than 25% are considered. The gray region represents the path of high-eccentricity migration with a range of 0.034–0.1 AU in the final semimajor axis and is set by the Roche limit and the circularization timescale. The giant planets are color-coded according to their host’s metallicity. Triangles represent planets with P < 3 days, diamonds 3 < P < 10 days, and circles P > 10 days. The position of TOI-4603 b is marked with an arrow.
