TEMPERATURE STRUCTURE AND ATMOSPHERIC CIRCULATION OF DRY TIDALLY LOCKED ROCKY EXOPLANETS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Next-generation space telescopes will observe the atmospheres of rocky planets orbiting nearby M-dwarfs. Understanding these observations will require well-developed theory in addition to numerical simulations. Here we present theoretical models for the temperature structure and atmospheric circulation of dry, tidally locked ...

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.

Thermoelastic Contraction as a Suppressor of Atmospheric Escape in Close-in Exoplanets
The Astrophysical JournalThe survival of volatile-rich atmospheres on close-in exoplanets challenges classical escape models. We identify a fully classical, interior-driven correction: thermoelastic contraction of the planetary mantle slightly increases the gravitational binding

Ohmic Dissipation During the Formation of Super-Earth
The Astrophysical Journal, 2023 The super-Earth population, as one of the representatives of exoplanets, plays an important role in constraining the planet formation theories. According to the prediction from core-accretion models, super-Earths should be rare because their masses are ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, Volume 17, Issue 4, Page 553-565, September 2026.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]
, 2014 The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

Oxidation of the Interiors of Carbide Exoplanets
The Planetary Science Journal, 2020 Astrophysical measurements have shown that some stars have sufficiently high carbon-to-oxygen ratios such that the planets they host would be mainly composed of carbides instead of silicates.

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Saturn's Kilometric Radiation (SKR) is a powerful non‐thermal radio auroral emission produced by the Cyclotron Maser Instability (CMI), which generates waves close to the local cyclotron frequency in a highly magnetized plasma from mildly relativistic electrons.

Impacting Atmospheres: How Late-stage Pollution Alters Exoplanet Composition
The Astrophysical JournalThe atmospheric composition of exoplanets is often considered as a probe of the planet’s formation conditions. How exactly the initial chemical memory may be altered from the birth to the final state of the planet, however, remains unknown.
