Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities

open access: yesAGU Advances, Volume 7, Issue 5, August 2026.
Abstract Numerical simulations play an essential role in the study of ionospheric irregularities. In the past few decades, electrostatic simulations have successfully simulated the nonlinear evolution of terrestrial ionospheric irregularities. However, the Mars Atmosphere and Volatile EvolutioN (MAVEN) observations reveal that the Martian ionospheric ...

A Theory for the Global Wind Energy Dissipation Across Climates

open access: yesAGU Advances, Volume 7, Issue 5, August 2026.
Abstract Atmospheric winds play a key role in shaping climate, ecosystems, and infrastructure. The energy that drives the winds is generated by the atmospheric heat engine. However, traditional entropy‐budget descriptions of this heat engine rely on poorly constrained microscale processes, limiting their predictive power.

Abundances in Stars with Exoplanets [PDF]

open access: yesSymposium - International Astronomical Union, 2004
Extensive spectroscopic studies of stars with and without planets have concluded that stars hosting planets are significantly more metal-rich than those without planets. More subtle trends of different chemical elements begin to appear as the number of detected extrasolar planetary systems continues to grow.

The Impact of Stellar Surface Magnetoconvection and Oscillations on the Detection of Temperate, Earth-Mass Planets Around Sun-Like Stars

open access: yesGeosciences, 2019
Detecting and confirming terrestrial planets is incredibly difficult due to their tiny size and mass relative to Sun-like host stars. However, recent instrumental advancements are making the detection of Earth-like exoplanets technologically feasible ...

Search of Exoplanets - Phase I

open access: yes, 2008
From the Astronomical Observatory at the University of Nariño-COLOMBIA, we have begun a systematic search for exoplanets. Initially we made differential photometry on variable stars weaker than the tenth magnitude to get enough experience on the ...

Microlensing and Its Degeneracy Breakers: Parallax, Finite Source, High-Resolution Imaging, and Astrometry

open access: yesUniverse, 2017
First proposed by Paczynski in 1986, microlensing has been instrumental in the search for compact dark matter as well as discovery and characterization of exoplanets.

Characterization of Exoplanets with LIFE (Large Interferometer For Exoplanets)

open access: yes
The ESA Voyage 2050 report (https://www.cosmos.esa.int/web/voyage-2050) names the “characterisation of temperate exoplanets in the mid-infrared, through a first spectrum of direct thermal emission from exoplanet atmospheres to better understand if they harbour truly habitable surface conditions” as one of the top three priorities ...
