Tidal Evolution of Close-in Exoplanets and Host Stars

open access: greenMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT The evolution of exoplanetary systems with a close-in planet is ruled by the tides mutually raised on the two bodies and by the magnetic braking of the host star. This paper deals with consequences of this evolution and some features that can be observed in the distribution of the systems' two main periods: the orbital period ...

Thermal and Orbital Evolution of Low-mass Exoplanets [PDF]

open access: bronzeThe Astrophysical Journal, 2020
Abstract The thermal, orbital, and rotational dynamics of tidally loaded exoplanets are interconnected by intricate feedback. The rheological structure of the planet determines its susceptibility to tidal deformation and, as a consequence, participates in shaping its orbit.

Long-term evolution of exoplanet systems

open access: hybridProceedings of the International Astronomical Union, 2022
AbstractIn this Review, I discuss recent developments on the long-term dynamical evolution of exoplanet systems, focusing on how distinctive dynamical processes may have shaped the orbital architectures of observed populations. I include three applications that highlight part of my own work. First, I examine the high-eccentricity tidal migration of hot

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]

open access: goldJournal of Astronomy and Space Sciences, 2016
A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Mapping out the time-evolution of exoplanet processes [PDF]

open access: green, 2019
There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make such a characterization increase, we begin to see pathways forward for validating these theories.

The evolution of stellar surface activity and possible effects on exoplanets [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2010
AbstractThe evolution of stellar activity involves a complex interplay between the interior dynamo mechanism, the emergent magnetic field configurations and their coupling with stellar winds, the subsequent angular momentum evolution, and fundamental stellar parameters.

Tidal evolution of close-in exoplanets in co-orbital configurations [PDF]

open access: bronzeCelestial Mechanics and Dynamical Astronomy, 2013
In this paper, we study the behavior of a pair of co-orbital planets, both orbiting a central star on the same plane and undergoing tidal interactions. Our goal is to investigate final orbital configurations of the planets, initially involved in the 1/1 mean-motion resonance (MMR), after long-lasting tidal evolution.

Effect of Galactic Chemical Evolution on Exoplanet Properties [PDF]

open access: greenThe Astrophysical Journal Letters
Abstract We couple a simplified model for galactic chemical evolution with software that models the condensation of dust in protoplanetary disks and software that models the interior structure of planets, in order to estimate the effects that galactic chemical evolution has on the properties of planets as they form over time.
