Polarimetry of exoplanet-exomoon systems
Astronomy & AstrophysicsAims. We investigated the potential of polarimetric observations in the optical wavelength range for the detection of exomoons and the characterization of exoplanet-exomoon systems. Methods. Using the three-dimensional Monte Carlo radiative transfer code POLARIS, we calculated flux and polarization phase curves of Earth-like exoplanets with a satellite

The Astronomical Journal, 2023 Directly imaging temperate rocky planets orbiting nearby, Sun-like stars with a 6 m class IR/O/UV space telescope, recently dubbed the Habitable Worlds Observatory, is a high-priority goal of the Astro2020 Decadal Survey.

Statistical Distribution Function of Orbital Spacings in Planetary Systems
The Astronomical JournalThe minimum orbital separation of planets in long-stable planetary systems is often modeled as a step function, parameterized with a single value ${{\rm{\Delta }}}_{\min }$ (measured in mutual Hill radius of the two neighboring planets).

The Astronomical Journal, 2023 In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total.

Gaia astrometry and exoplanetary science: DR2, (E)DR3, and beyond
Comptes Rendus. Physique, 2023 I review the recent impact of Gaia astrometry in the exoplanet field, both in terms of characterization of the orbits and masses of planetary systems and the properties of their host stars.

UniverseThe distribution of period ratios for 580 known two-planet systems is apparently nonuniform, with several sharp peaks and troughs. In particular, the vicinity of the 2:1 commensurability seems to have a deficit of systems.

Exoplanet orbital eccentricity: Multiplicity relation and the Solar System [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance The Solar System planets have near-circular orbits (i.e., unusually low eccentricity) compared with the known population of exoplanets, planets that orbit stars other than the Sun. This fact has been widely interpreted to indicate that the Solar System is an atypical member of the overall population of planetary systems.

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System
The Astronomical Journal, 2023 The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events
Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.
