The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect

Universe, 2023
Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

One-Dimensional Convolutional Neural Networks for Detecting Transiting Exoplanets

Axioms, 2023
The transit method is one of the most relevant exoplanet detection techniques, which consists of detecting periodic eclipses in the light curves of stars.

Transiting Circumbinary Planets in the Era of Space-Based Photometric Surveys

Universe, 2023
Planets orbiting binary stars—circumbinary planets—play a paramount role in our understanding of planetary and stellar formation and evolution, dynamical interactions in many-body systems, and the potential for habitable environments beyond the Solar ...

Orbital Period Refinement of CoRoT Planets with TESS Observations

Frontiers in Astronomy and Space Sciences, 2021
CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first terrestrial exoplanet with a measured size. The precision of the published

Characterization of a Set of Small Planets with TESS and CHEOPS and an Analysis of Photometric Performance

The Astronomical Journal, 2023
The radius valley carries implications for how the atmospheres of small planets form and evolve, but this feature is visible only with highly precise characterizations of many small planets.

The Breakthrough Listen Search for Intelligent Life: Detection and Characterization of Anomalous Transits in Kepler Lightcurves

The Astronomical Journal, 2023
Never before has the detection and characterization of exoplanets via transit photometry been as promising and feasible as it is now, due to the increasing breadth and sensitivity of time domain optical surveys.

Comparison of visual and acoustic surveys for the detection and dynamic management of North Atlantic right whales (Eubalaena glacialis) in Canada

Conservation Science and Practice, 2023
The goal of this study was to develop a simulation to quantitatively compare acoustic and visual surveys and use it to inform current and future North Atlantic right whale (Eubalaena glacialis) risk mitigation.

Revisiting the transits of CoRoT-7b at a lower activity level [PDF]

, 2014
CoRoT-7b, the first super-Earth with measured radius discovered, has opened the new field of rocky exoplanets characterisation. To better understand this interesting system, new observations were taken with the CoRoT satellite.
