TOI-1736 and TOI-2141 SOPHIE observations
Listed in IVOA Registry (Virtual Observatory)
Planetary systems around solar analogs inform us about how planets form and evolve in solar system-like environments.
Description
We report the detection and characterization of two planetary systems around the solar analogs TOI-1736 and TOI-2141 using TESS photometry data and spectroscopic data obtained with the SOPHIE instrument on the 1.93 m telescope at the Observatoire de Haute-Provence (OHP). We performed a detailed spectroscopic analysis of these systems to obtain the precise radial velocities and physical properties of their host stars.
TOI-1736 and TOI-2141 each host a transiting sub-Neptune with radii of 2.44+/-0.18 and 3.05+/-0.23R_{Earth}_, orbital periods of 7.073088(7)d and 18.26157(6)d, and masses of 12.8+/-1.8M_{Earth}_ and 24+/-4M_{Earth}_, respectively. TOI-1736 shows long-term radial velocity variations that are consistent with a two-planet solution plus a linear trend of -0.177m/s/d. We measured an RV semi-amplitude of 201.1+/-0.7m/s for the outer companion, TOI-1736 c, implying a projected mass of msin(i)=8.09+/-0.20M_Jup_.

From the GAIA DR3 astrometric excess noise, we constrained the mass of TOI-1736 c at 8.7+/-1.5M_{Jup}_. This planet is in an orbit of 570.2+/-0.6d with an eccentricity of 0.362+/-0.003 and a semi-major axis of 1.381+/-0.017au, where it receives a flux of 0.71+/-0.08 times the bolometric flux incident on Earth, making it an interesting case of a supergiant planet that has settled into an eccentric orbit in the habitable zone of a solar analog.
Our analysis of the mass-radius relation for the transiting sub-Neptunes shows that both TOI-1736 b and TOI-2141 b likely have an Earth-like dense rocky core and a water-rich envelope.
