Conference “Modern Stellar Astronomy 2017”

open access: yesOpen Astronomy, 2017
Here we give a brief overview on the eighth annual conference on Modern Stellar Astronomy held in the Ural FederalUniversity (Ekaterinbourg, Russia) in June 2017, to commemorate the 100th birthday of Prof. K. Barkhatova (1917-1990).

OnAIR: Applications of the NASA on‐board artificial intelligence research platform

open access: yesAI Magazine, Volume 46, Issue 3, Fall 2025.
Abstract Infusing artificial intelligence algorithms into production aerospace systems can be challenging due to costs, timelines, and a risk‐averse industry. We introduce the Onboard Artificial Intelligence Research (OnAIR) platform, an open‐source software pipeline and cognitive architecture tool that enables full life cycle AI research for on‐board ...

Biosignatures Search in Habitable Planets

open access: yesGalaxies, 2019
The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of planets, from hot giants to rocky planets orbiting small

Exoplanet Predictions Based on Harmonic Orbit Resonances

open access: yes, 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.

Characterizing Exoplanet Habitability [PDF]

open access: yes, 2017
A habitable exoplanet is a world that can maintain stable liquid water on its surface. Techniques and approaches to characterizing such worlds are essential, as performing a census of Earth-like planets that may or may not have life will inform our understanding of how frequently life originates and is sustained on worlds other than our own ...

Re‐Analysis of Pioneer Venus Data: Water, Iron Sulfate, and Sulfuric Acid are Major Components in Venus' Aerosols

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We present a new and transformative composition for Venus' cloud aerosols using previously uncharacterized data acquired by the Pioneer Venus Large Probe, which descended through Venus' atmosphere in 1978. This aerosol composition was extracted by re‐analyzing data acquired by the Large Probe Neutral Mass Spectrometer (LNMS) and re‐evaluating ...

Microlensing Searches for Exoplanets [PDF]

open access: yesGeosciences, 2018
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the lensing event, even if no light is detectable from the planet or the host foreground star.

The “Analogs for VENus' GEologically Recent Surfaces” (AVENGERS) Initiative: Using Terrestrial Analogs to Study Recent Volcano‐Tectonic Activity on Venus and Inform the Characterization of Terrestrial Exoplanets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Several missions to Venus have recently been selected for launch, opening a new era for the exploration of the planet. A key question these missions seek to address is whether Venus is geologically active today. Detecting active volcanism on Venus would contribute to a better understanding of volcanic and atmospheric processes on Earth.

Diversity of exoplanets

open access: yes
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.
