Impacts of Tidal Locking on Magnetospheric Energy Input to Exoplanet Atmospheres

Astrophysical Journal
We investigate the effect of planetary corotation on energy dissipation within the magnetosphere–ionosphere system of exoplanets. Using magnetohydrodynamic simulations, we find that tidally locked exoplanets have a higher cross polar cap potential (CPCP)

Dynamic analyses of the proposed Habitable Exoplanet Astrophysics Facility

Optical Modeling and System Alignment, 2019
The proposed Habitable Exoplanet (HabEx) astrophysics facility is one of four large such facilities being proposed to the 2020 decadal. It is a large telescope that is sensitive to ultraviolet, optical, and near-infrared photons. The proposed design’s overall length is on the order of 17.2 m and its maximum cross section is on the order of 5.25 X 5.25 ...

Exoplanet Atmospheres with HST: An open science framework for the characterisation of exoplanets

, 2020
The field of exoplanets is one of the most rapidly growing, with more than 4000 new planets discovered over the past 25 years. In the last decade, we have entered in a new era, the era of exoplanet characterisation, where studies are also focused on ...

TO THE ORBITAL DYNAMICS WITH VARIABLE ECCENTRICITY

Reports
In this work, we study the orbital dynamics of the non-stationary gravitating system. We consider eccentricity as a function of time, because of its plenty interesting implications for evolution of young planetary systems.

Revealing the dynamical properties of Jupiter-size exoplanets on elliptic orbits

Chaos, Solitons & Fractals
Our study delves into the orbital dynamics of an exoplanetary system, comprising a solar-mass host star, a transiting Jupiter-sized body, and an Earth-sized exoplanet. This exploration is grounded in the general three-body problem framework. We undertake a comprehensive and systematic numerical analysis of the available phase space, employing a ...

The long-term tidal dynamics of differentiated rocky exoplanets

OverviewTidal interaction plays a unique role in coupling the thermal, orbital, and rotational evolution of close-in moons and exoplanets. The reaction of a planetary body subjected to tidal loading is determined by its interior structure, rheological properties, and orbital parameters. The interior and orbital dynamics are, conversely, affected by the

Discovery, Characterization, and Dynamics of Transiting Exoplanets

2015
Are we alone in the Universe? So far, the question remains unanswered, but a significant leap forward was achieved two decades ago, with the discovery of the first planets orbiting stars other than our Sun. Almost 2000 exoplanets have now been detected.
