Chromospheric activity of stars with planets
(Astronomy & Astrophysics, 2011)
Study of the impact of the post-MS evolution of the host star on the orbits of close-in planets. II. A giant planet in a close-in orbit around the RGB star HIP 63242
(EDP Sciences, 2013)
Context. More than 40 planets have been found around giant stars, revealing a lack of systems orbiting interior to ∼0.6 AU. This
observational fact contrasts with the planetary population around solar-type stars and has ...
Interplay of tidal evolution and stellar wind braking in the rotation of stars hosting massive close-in planets
(The American Astronomical Society, 2020)
No evidence of the planet orbiting the extremely metal-poor extragalactic star HIP 13044
(ESO, 2014)
Context. The recent discovery of three giant planets orbiting the extremely metal-poor stars HIP 11952 and HIP 13044 have challenged
theoretical predictions of the core-accretion model. According to this, the metal content ...
The properties of planets around giant stars
(EDP SCIENCES S A, 2014)
Context. More than 50 exoplanets have been found around giant stars, revealing different properties when compared to planets orbiting solar-type stars. In particular, they are super-Jupiters and are not found orbiting ...
A hot Saturn on an eccentric orbit around the giant star K2-132
(EDP Sciences, 2018)
Although the majority of radial velocity detected planets have been found orbiting solar-type stars, a fraction of them have been discovered around giant stars. These planetary systems have revealed different orbital ...
Semianalytical model for planetary resonances: Application to planets around single and binary stars
(EDP Sciences, 2021-02)
Context. Planetary resonances are a common dynamical mechanism acting on planetary systems. However, no general model for describing their properties exists, particularly for commensurabilities of any order and arbitrary ...
Magnetized winds and their influence in the escaping upper atmosphere of HD 209458b
(Wiley Blackwell Publishing, Inc, 2018-09)
Lyman a observations during an exoplanet transit have proved to be very useful to study the interaction between the stellar wind and the planetary atmosphere. They have been extensively used to constrain planetary system ...
