Query: Coralie radial-velocity search for companions around evolved stars
  (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using
  TESS data   Context. Increasing the number of detected exoplanets is far from anecdotal,
especially for long-period planets that require a long duration of observation.
More detections imply a better understanding of the statistical properties of
exoplanet populations, and detailed modelling of their host stars also enables
thorough discussions of star-planet interactions and orbital evolution of
planetary systems. Aims. In the context of the discovery of a new planetary
system, we aim to perform a complete study of HD 29399 and its companion by
means of radial-velocity measurements, seismic characterisation of the
host-star, and modelling of the orbital evolution of the system. Methods.
High-resolution spectra of HD 29399 were acquired with the CORALIE spectrograph
mounted on the 1.2- m Swiss telescope located at La Silla Observatory (Chile)
as part of the CASCADES survey. We used the moments of the cross-correlation
function profile as well as the photometric variability of the star as
diagnostics to distinguish between stellar and planetary-induced signals. To
model the host star we combined forward modelling with global and local
minimisation approaches and inversion techniques. We also studied the orbital
history of the system under the effects of both dynamical and equilibrium
tides. Results. We present the detection of a long-period giant planet.
Combining these measurements with photometric observations by TESS, we are able
to thoroughly model the host star and study the orbital evolution of the
system. We derive stellar and planetary masses of $1.17 \pm 0.10~ M_{\odot}$
and $1.59 \pm 0.08 ~M_{Jup}$, respectively, and an age for the system of 6.2
Gyr. We show that neither dynamical nor equilibrium tides have been able to
affect the orbital evolution of the planet. Moreover, no engulfment is
predicted for the future evolution of the system.
