An extended hydrogen envelope of the extremely hot giant exoplanet KELT-9b

Nature Astronomy, 2018
Giant exoplanets orbiting close to their host stars have high temperatures because of the immense amount of stellar irradiation that they receive. The extreme energy input leads to the expansion of the atmosphere and the escape of neutral hydrogen1–3. An

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 ...

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)

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.

Radiative Flux from a High-resolution Atmospheric Dynamics Simulation of a Hot Jupiter for JWST and Ariel

Astrophysical Journal
We present medium-wave (∼0.5–13 μm) radiative flux distributions and spectra derived from high-resolution atmospheric dynamics simulations of an exoplanet, WASP-121 b. This planet serves to illustrate several important features.

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
