CoRoT pictures transiting exoplanets

, 2015
The detection and characterization of exoplanets have made huge progresses since the first discoveries in the late nineties. In particular, the independent measurement of the mass and radius of planets, by combining the transit and radial-velociy ...

On the Detection of Molecules in the Atmosphere of HD189733b using HST NICMOS Transmission Spectroscopy

, 2014
The HST/NICMOS transmission spectrum measurements of HD 189733b that suggest the detection of methane (CH$_{4}$) in an exoplanet atmosphere have been a source of significant controversy. With what is probably the best analyzed exoplanet spectroscopy data

Validation of the Exoplanet Kepler-21b using PAVO/CHARA Long-Baseline Interferometry [PDF]

, 2012
We present long-baseline interferometry of the Kepler exoplanet host star HD179070 (Kepler-21) using the PAVO beam combiner at the CHARA Array. The visibility data are consistent with a single star and exclude stellar companions at separations ~1-1000 ...

Leveraging Multimodal Large Language Models to Analyse Student Exploration Behaviours in Educational Game Environments

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Video data provides rich opportunities to examine student behaviour in game‐based learning environments, capturing not only observable actions but also subtle indicators of cognitive engagement. However, traditional video analysis is labor‐intensive, and current applications of AI to this task are limited by models trained on ...

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

The Astrophysical Journal Letters
Though missions such as Kepler, K2, and TESS have discovered >2000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in ( P ≲ 3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be

Multiplicity Boost of Transit Signal Classifiers: Validation of 69 New Exoplanets using the Multiplicity Boost of ExoMiner

The Astronomical Journal, 2023
Most existing exoplanets are discovered using validation techniques rather than being confirmed by complementary observations. These techniques generate a score that is typically the probability of the transit signal being an exoplanet ( y ( x ...

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 ...

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Identifying Exoplanets with Deep Learning. V. Improved Light-curve Classification for TESS Full-frame Image Observations

The Astronomical Journal, 2023
The TESS mission produces a large amount of time series data, only a small fraction of which contain detectable exoplanetary transit signals.
