Tidal Evolution of Exoplanets

, 2010
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an equilibrium situation is reached. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous ...

Evidence for a Natural Limit to Electron Space Radiation: An Application of Benford's Law

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Recent research has highlighted observational evidence for a natural limit to the severity of energetic electron differential fluxes in the Van Allen radiation belts. Here, we analyze the occurrence distributions of electron differential fluxes from the entire Van Allen Probes mission (2012–2019) to further investigate the energy dependence of

Infrared-radio-follow-up observations for detection of the magnetic radio emission of extra solar planets: a new window to detect exoplanets

Frontiers in Astronomy and Space Sciences
There are several methods for indirectly detecting exoplanets, such as transit, radial velocity, astrometry, and the conventional gravitational microlensing approach.

Search for possible exomoons with FAST telescope

, 2017
Our knowledge of the Solar System, encourages us to beleive that we might expect exomoons to be present around some of the known exoplanets. With present hardware and existing optical astronomy methods we shall not be able to find exomoons at least 10 ...

The Demographics Of Exoplanets

, 2018
Bridge Talk. Part I: Making a Hot Jupiter; the planet that shouldn't be there (P. Figueira). Part II: The Grand Tack; Jupiter & Saturn's migration in the gas disk (A. Crida). Part III: The NICE model; global instability in the giant planets' architecture after dispersal of the gas disk.

On the Measurement of Ocean Acidity With Ambient Sound

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract The volume‐integrated pH of seawater can be determined from the frequency and depth dependence of wind‐generated ambient noise in the ocean. Over the 1–10 kHz frequency band, three main processes contribute to the acoustic attenuation in seawater: the chemical relaxation of boric acid and magnesium carbonate (<3 kHz, related to pH) and of ...

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

Radiogenic Power and Geoneutrino Luminosity of the Earth and Other Terrestrial Bodies Through Time

Geochemistry, Geophysics, Geosystems, 2020
We report the Earth's rate of radiogenic heat production and (anti)neutrino luminosity from geologically relevant short‐lived radionuclides (SLR) and long‐lived radionuclides (LLR) using decay constants from the geological community, updated nuclear ...

On the Fundamental Mass-Period Functions of Extrasolar Planets

, 2009
Employing a catalog of 175 extrasolar planets (exoplanets) detected by the Doppler-shift method, we constructed the independent and coupled mass-period functions.

Electrical Resistivity of Liquid Fe‐16S‐2Si up to 13 GPa With Implications for the Adiabatic Heat Flux Through the Core of Exoplanet TRAPPIST‐1h

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Thermal convective processes in the liquid cores of terrestrial planetary bodies with the capacity to generate magnetic dynamos may be better characterized by thermal conductivity estimates of core conditions. The composition of the core of asteroid 4 Vesta as determined by geochemical studies of HED meteorites is used as an analog for the ...
