Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.Under extreme pressure and temperature, superionic water acts as a strong superacid, catalyzing methane polycondensation through pentacoordinated carbonium ions (CH5+). This discovery reveals the non‐classical carbocation chemistry underlying the early stages of diamond formation in water under extreme conditions.

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets
, 2011 We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq ...

Adaptive Optics Observations of Exoplanets, Brown Dwarfs, & Binary Stars [PDF]
, 2011 The current direct observations of brown dwarfs and exoplanets have been obtained using instruments not specifically designed for overcoming the large contrast ratio between the host star and any wide-separation faint companions. However, we are about to

Exoplanet Predictions Based on Harmonic Orbit Resonances
, 2017 The current exoplanet database includes 5454 confirmed planets and candidate planets observed with the KEPLER mission. We find 932 planet pairs from which we extract distance and orbital period ratios.

The contribution of the major planet search surveys to EChO target selection [PDF]
, 2014 The EChO core science will be based on a three tier survey, each with increasing sensitivity, in order to study the population of exo-planets from super-Earths to Jupiter-like planets, in the very hot to temperate zones (temperatures of 300 K - 3000 K ...

Searching for Exoplanets Using a Microresonator Astrocomb [PDF]
Nature Photonics, 2018 Orbiting planets induce a weak radial velocity (RV) shift in the host star that provides a powerful method of planet detection. Importantly, the RV technique provides information about the exoplanet mass, which is unavailable with the complementary ...

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59
Astronomische Nachrichten, EarlyView.ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

A generalized bayesian inference method for constraining the interiors of super Earths and sub-Neptunes [PDF]
, 2016 We aim to present a generalized Bayesian inference method for constraining interiors of super Earths and sub-Neptunes. Our methodology succeeds in quantifying the degeneracy and correlation of structural parameters for high dimensional parameter spaces ...

VISIBLE AND INFRARED TELESCOPES IN DETECTION OF EARTH-LIKE EXOPLANETS
Radio Physics and Radio Astronomy, 2016 Object and purpose: The study examines the balance of resolving and light-harvesting (penetrating) abilities of filled and sparse aperture telescopes in direct detection of terrestrial exoplanets.
