Research Progress on Atmospheric Turbulence Perception and Correction Based on Adaptive Optics and Deep Learning

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
This work presents a systematic review of atmospheric turbulence fundamentals, including theoretical formulations and adaptive optics‐based mitigation strategies. This includes an in‐depth examination of the devices, theories, and methodologies associated with traditional correction approaches.

Kepler Observations of the Three Pre-Launch Exoplanet Candidates: Discover of Two Eclipsing Binaries and a New Exoplanet [PDF]

, 2010
Three transiting exoplanet candidate stars were discovered in a ground-based photometric survey prior to the launch of NASA's Kepler mission. Kepler observations of them were obtained during Quarter 1 of the Kepler mission.

Exoplanet Transit Database. Reduction and processing of the photometric data of exoplanet transits

, 2009
We demonstrate the newly developed resource for exoplanet researchers - The Exoplanet Transit Database. This database is designed to be a web application and it is open for any exoplanet observer. It came on-line in September 2008.

Zehn Jahre Gaia‐Messungen: Die hochgenaue Kartierung des Himmels

Physik in unserer Zeit, Volume 56, Issue 4, Page 175-183, July 2025.
Das astrometrische Weltraumobservatorium Gaia der Europäischen Weltraumorganisation hat die astrometrische Forschung revolutioniert, indem es unter anderem präzise Positionen, Bewegungen und Entfernungen von fast zwei Milliarden Himmelsobjekten gemessen hat. Damit stellt es wertvolle Daten für fast alle Gebiete der Astrophysik bereit. Nach dem Ende der

Tidal Evolution of Exoplanets

, 2010
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an equilibrium situation is reached. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous ...

Theoretical Spectra of Terrestrial Exoplanet Surfaces [PDF]

, 2012
We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si-O features in ...

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Analysis of Habitability and Stellar Habitable Zones from Observed Exoplanets

Galaxies
The investigation of exoplanetary habitability is integral to advancing our knowledge of extraterrestrial life potential and detailing the environmental conditions of distant worlds. In this analysis, we explore the properties of exoplanets situated with

Transiting Exoplanet Studies and Community Targets for JWST's Early Release Science Program [PDF]

, 2016
The James Webb Space Telescope will revolutionize transiting exoplanet atmospheric science due to its capability for continuous, long-duration observations and its larger collecting area, spectral coverage, and spectral resolution compared to existing ...
