- W4308721369 abstract "Kepler-33 hosts five validated transiting planets ranging in period from 5 to 41 days. The planets are in nearly co-planar orbits and exhibit remarkably similar (appropriately scaled) transit durations indicative of similar impact parameters. The outer three planets have radii of $3.5lesssim R_{rm p}/R_opluslesssim4.7$ and are closely-packed dynamically, and thus transit timing variations can be observed. Photodynamical analysis of transit timing variations provide $2sigma$ upper bounds on the eccentricity of the orbiting planets (ranging from $<0.02$ to $<0.2$) and the mean density of the host-star ($0.39_{-0.02}^{+0.01},{rm g/cm^3}$). We combine emph{Gaia} Early Data Release 3 parallax observations, the previously reported host-star effective temperature and metallicity, and our photodynamical model to refine properties of the host-star and the transiting planets. Our analysis yields well-constrained masses for Kepler-33~e ($6.6_{-1.0}^{+1.1},M_oplus$) and f ($8.2_{-1.2}^{+1.6},M_oplus$) along with $2sigma$ upper limits for planets c ($<19,M_oplus$) and d ($<8.2,M_oplus$). We confirm the reported low bulk densities of planet d ($<0.4,{rm g/cm^3}$), e ($0.8pm0.1,{rm g/cm^3}$), and f ($0.7pm0.1,{rm g/cm^3}$). Based on comparisons with planetary evolution models, we find that Kepler-33~e and f exhibit relatively high envelope mass fractions of $f_{rm env}=7.0_{-0.5}^{+0.6}%$ and $f_{rm env}=10.3pm0.6%$, respectively. Assuming a mass for planet d $sim4,M_oplus$ suggests that it has $f_{rm env}gtrsim12%$." @default.
