The Rotation of Planet-Hosting Stars
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Understanding the distribution of angular momentum during the formation of planetary systems is a key topic in astrophysics. Data from the Kepler and Gaia missions allow to investigate whether stellar rotation is correlated with the presence of planets around Sun-like stars.

Revising the Ages of Planet-Hosting Stars [PDF]
Astronomy and Astrophysics, 2015 This article aims to measure the age of planet-hosting stars (SWP) through stellar tracks and isochrones computed with the \textsl{PA}dova \& T\textsl{R}ieste \textsl{S}tellar \textsl{E}volutionary \textsl{C}ode (PARSEC). We developed algorithms based on two different techniques for determining the ages of field stars: \emph{isochrone placement ...

Bimodality in Rotational Modulation of Planet-hosting Stars
The Astrophysical Journal LettersStellar magnetic activity is governed by the interplay between rotation, convection, and the temporal evolution of surface magnetic structures, yet the role of planetary systems in shaping these processes remains unclear.

Metallicities of Planet-Hosting Stars: A Sample of Giants and Subgiants [PDF]
Astrophysical Journal, 2010 This work presents a homogeneous derivation of atmospheric parameters and iron abundances for a sample of giant and subgiant stars which host giant planets, as well as a control sample of subgiant stars not known to host giant planets. The analysis is done using the same technique as for our previous analysis of a large sample of planet-hosting and ...

Disruption of a Planet Spiraling into its Host Star [PDF]
The Astrophysical Journal, 2018 Abstract The processes leading to the deformation and destruction of planets spiraling into the convective envelope of their host stars are described. The planet is compressed by ram pressure and deformed into a flattened shape, for which a quantitative model is developed.

The Astronomical Journal, 2023 Orbital eccentricity is one of the basic planetary properties, whose distribution may shed light on the history of planet formation and evolution. Here, in a series of works on Planetary Orbit Eccentricity Trends (dubbed POET), we study the distribution ...

Asteroseismic investigation of 20 planet and planet-candidate host stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT Planets and planet candidates are subjected to great investigation in recent years. In this study, we analyse 20 planet and planet-candidate host stars at different evolutionary phases. We construct stellar interior models of the host stars with the mesa e.volution code and obtain their fundamental parameters under influence of ...
