TOI-2046b, TOI-1181b and TOI-1516b, three new hot Jupiters from \textit{TESS}: planets orbiting a young star, a subgiant and a normal star
We present the confirmation and characterization of three hot Jupiters,
TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The
reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The
masses of the three planets are M, \,
M, and 2.30 M, for TOI-1181b,
TOI-1516b, and TOI-2046b, respectively. The stellar host of TOI-1181b is a F9IV
star, whereas TOI-1516b and TOI-2046b orbit F main sequence host stars. The
ages of the first two systems are in the range of 2-5 Gyrs. However, TOI-2046
is among the few youngest known planetary systems hosting a hot Jupiter, with
an age estimate of 100-400 Myrs. The main instruments used for the radial
velocity follow-up of these three planets are located at Ond\v{r}ejov,
Tautenburg and McDonald Observatory, and all three are mounted on 2-3 meter
aperture telescopes, demonstrating that mid-aperture telescope networks can
play a substantial role in the follow-up of gas giants discovered by
\textit{TESS} and in the future by \textit{PLATO}.Comment: MNRAS accepte
