THE IMPACT OF NON-UNIFORM THERMAL STRUCTURE ON THE INTERPRETATION OF EXOPLANET EMISSION SPECTRA [PDF]
The Astrophysical Journal, 2016 ABSTRACT The determination of atmospheric structure and molecular abundances of planetary atmospheres via spectroscopy involves direct comparisons between models and data. While varying in sophistication, most model spectra comparisons fundamentally assume one-dimensional (1D) model physics.

Irradiated Atmospheres. IV. Effect of Mixing Heat Flux on Chemistry
The Astrophysical JournalVertical mixing disrupts the thermochemical equilibrium and introduces additional heat flux that alters exoplanetary atmospheric temperatures. We investigate how this mixing-induced heat flux affects atmospheric chemistry.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

Most Super-Earths Have Less Than 3% Water
The Astrophysical JournalSuper-Earths are highly irradiated, small planets with bulk densities approximately consistent with Earth. We construct combined interior atmosphere models of super-Earths that trace the partitioning of water throughout a planet, including an iron-rich ...

Out There No One Has a Right to Die
Bioethics, Volume 40, Issue 6, Page 565-572, July 2026.ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Characterizing Exoplanets for Assessing Their Potential Habitability
The Astrophysical JournalThe Statistical-likelihood Exoplanetary Habitability Index (SEPHI) serves as a valuable tool for prioritizing targets for further study and identifying potentially habitable environments.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

Distinguishing Oceans of Water from Magma on Mini-Neptune K2-18b
The Astrophysical Journal LettersMildly irradiated mini-Neptunes have densities potentially consistent with them hosting substantial liquid-water oceans (“Hycean” planets). The presence of CO _2 and simultaneous absence of ammonia (NH _3 ) in their atmospheres has been proposed as a ...

Effects of Hot Oxygen Corona on Ion Escape From Venus‐Like Planets
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Due to the lack of a significant planetary magnetic field, the upper atmospheres of Venus‐like planets interact directly with the stellar wind. Therefore, thermal atomic oxygen in the thermosphere and hot oxygen in the corona produced by non‐thermal processes in the upper atmosphere act as a source of ion pickup loss.
