RV (top panel) and FWHM (bottom panel) time-series. The purple markers in each panel represent the HARPS RV and FWHM measurements with inferred offsets extracted. The inferred multi-GP model is shown as a solid black curve, where the dark and light shaded areas show the 1- and 2- sigma credible intervals from said model, and can also explain the data but with a correspondingly lower probability. The solid red line in the top panel shows the star-only model, while the teal sine curve the Keplerian for TOI-733 b. In both panels the nominal error bars are in solid purple, and the jitter error bars (HARPS) are semi-transparent purple. astro-ph.EP
We report the discovery of a hot (Teq 1055 K) planet in the small planet radius valley transiting the Sun-like star TOI-733, as part of the KESPRINT follow-up program of TESS planets carried out with the HARPS spectrograph. TESS photometry from sectors 9 and 36 yields an orbital period of Porb = 4.884765+1.9e52.4e5 days and a radius of Rp = 1.992+0.0850.090 R.
Multi-dimensional Gaussian process modelling of the radial velocity measurements from HARPS and activity indicators, gives a semi-amplitude of K = 2.230.26 m s1, translating into a planet mass of Mp = 5.72+0.700.68 M. These parameters imply that the planet is of moderate density (p = 3.98+0.770.66 g cm3) and place it in the transition region between rocky and volatile-rich planets with H/He-dominated envelopes on the mass-radius diagram.
Combining these with stellar parameters and abundances, we calculate planet interior and atmosphere models, which in turn suggest that TOI-733 b has a volatile-enriched, most likely secondary outer envelope, and may represent a highly irradiated ocean world one of only a few such planets around G-type stars that are well-characterised.
