Stability of Proton Superoxide and its Superionic Transition Under High Pressure

Advanced Science, Volume 12, Issue 9, March 6, 2025.
The study predicts the stable proton superoxide (HO2) under extreme conditions using Density Functional Theory (DFT)‐based crystal structure prediction. HO2 exhibits metallic behavior at high pressure, transitions to an insulator under reduced pressure, and becomes superionic with high electrical conductivity under elevated temperatures.

Diversity of exoplanets

This review article delves into the study of low-mass exoplanets: super-Earths, mini-Neptunes and the new categories within and between that we are starting to discover. We provide an overview of current exoplanet observational capabilities, their limitations, and what they are allowing us to learn about low-mass planets.

Nitrates as a Potential N Supply for Microbial Ecosystems in a Hyperarid Mars Analog System

Life, 2019
Nitrate is common in Mars sediments owing to long-term atmospheric photolysis, oxidation, and potentially, impact shock heating. The Atacama Desert in Chile, which is the driest region on Earth and rich in nitrate deposits, is used as a Mars analog in ...

Toward an initial mass function for giant planets

, 2017
The distribution of exoplanet masses is not primordial. After the initial stage of planet formation is complete, the gravitational interactions between planets can lead to the physical collision of two planets, or the ejection of one or more planets from

Classification of Planetary Motion around Super-Jupiters and Brown Dwarfs

Universe
We investigate the orbital dynamics of an exosystem consisting of a solar-mass host star, a transiting body, and an Earth-size exoplanet within the framework of the generalized three-body problem.

Exoplanet phase curves: observations and theory

, 2018
Phase curves are the best technique to probe the three dimensional structure of exoplanets' atmospheres. In this chapter we first review current exoplanets phase curve observations and the particular challenges they face.

Effects of rotation and magnetic fields on the lithium abundance and asteroseismic properties of exoplanet-host stars

, 2010
Aims: The effects of rotation and magnetic fields on the surface abundances of solar-type stars are studied in order to investigate whether the reported difference in lithium content of exoplanet-host stars can be related to their rotational history ...

Notes on exoplanets

Journal of Physics: Conference Series, 2010
Our knowledge about exoplanets evolves rapidly. Here I give a short overview of some aspects of the exoplanet research and I also introduce shortly the reader to the Hungarian activities in the exoplanet field.
