The three inner planets have orbital periods of $\\approx8-24\\,{\\rm d}$ while the outer planet's period is poorly constrained by single transits observed with \\emph{K2} and \\emph{TESS}. Planets b, c, and d are proto-sub-Neptunes that may be undergoing significant mass loss. Depending on the stellar activity and planet masses, they are expected to evolve into super-Earths/sub-Neptunes that bound the radius valley.
