Search for possible exomoons with FAST telescope

, 2017
Our knowledge of the Solar System, encourages us to beleive that we might expect exomoons to be present around some of the known exoplanets. With present hardware and existing optical astronomy methods we shall not be able to find exomoons at least 10 ...

Exoplanet Occurrence Rate with Age for FGK Stars in Kepler

The Astronomical Journal
We measure the exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1–17 DR25 Kepler data. We employ Kepler's pipeline detection efficiency to correct for the expected number of

Grid-based Atmospheric Retrievals for Reflected-light Spectra of Exoplanets Using PSGnest

The Astronomical Journal, 2023
Techniques to retrieve the atmospheric properties of exoplanets via direct observation of their reflected light have often been limited in scope owing to computational constraints imposed by the forward-model calculations.

Exoplanet Detection Using Machine Learning : A Comparative Study Using Kepler Mission Data

International Journal of Scientific Research in Science and Technology
The search for habitable planets outside our solar system has captivated scientists throughout the centuries. Discovery and characterization of exoplanets have been one of the most important endeavors of modern astronomy.

Is OSSO a Significant Contributor to the Unknown UV Absorber in Venus' Atmosphere?

Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.
Abstract It has been proposed that two isomers of the SO dimer (cis‐ and trans‐OSSO) are candidates for the unknown UV absorber in Venus' atmosphere because they have a good spectral match with the absorber, despite the low concentrations predicted by 1D photochemical models.

Radiative Transfer for Exoplanet Atmospheres

, 2017
Remote sensing of the atmospheres of distant worlds motivates a firm understanding of radiative transfer. In this review, we provide a pedagogical cookbook that describes the principal ingredients needed to perform a radiative transfer calculation and ...

Friends Not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants

The Astrophysical Journal Letters
The connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies have been ...

Superhabitable Planets Around Mid‐Type K Dwarf Stars Enhance Simulated JWST Observability and Surface Habitability

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these “superhabitable” (SH) planets in the habitable zones around K dwarf stars has not been fully modeled. This study addresses this gap by modeling the atmospheres of SH exoplanets.

Initial Thermal States of Super‐Earth Exoplanets and Implications for Early Dynamos

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract The accretion of Earth and the formation of a metallic core released a large amount of primordial heat and may have enabled its evolution into a habitable world. Metal‐silicate segregation likely occurs in super‐Earth exoplanets as well, but its influence on their initial thermal states has not been fully examined.

Identifying Exoplanet Candidates Using WaveCeptionNet

The Astronomical Journal
In this study, we propose a wavelet-transform-based light curve representation method and a CNN model based on Inception-v3 for fast classification of light curves, enabling the quick discovery of potentially interesting targets from massive data ...
