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.

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.

System study of EPICS: the exoplanets imager for the E-ELT
SPIE Proceedings, 2010 ESO and a large European consortium completed the phase-A study of EPICS, an instrument dedicated to exoplanets direct imaging for the EELT. The very ambitious science goals of EPICS, the imaging of reflected light of mature gas giant exoplanets around bright stars, sets extremely strong requirements in terms of instrumental contrast achievable.

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).

Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

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.

New Phytologist, Volume 248, Issue 3, Page 1132-1153, November 2025.Summary One‐carbon (C1) metabolism, centered on the universal methyl donor S‐adenosyl methionine (SAM), plays critical roles in biosynthesis, redox regulation, and stress responses across plants and microbes. A recently proposed photosynthetic C1 pathway links SAM methyl groups directly to RuBisCO‐mediated CO2 assimilation and integrates with nitrogen ...

Using the inclinations of Kepler systems to prioritize new Titius-Bode-based exoplanet predictions [PDF]
, 2014 We analyse a sample of multiple-exoplanet systems which contain at least three transiting planets detected by the Kepler mission (‘Kepler multiples’). We use a generalized Titius– Bode relation to predict the periods of 228 additional planets in 151 of ...
