TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain

open access: yesThe Astronomical Journal, 2023
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±

The 0.5MJ transiting exoplanet WASP-13b [PDF]

open access: yes, 2009
We report the discovery of WASP-13b, a low-mass $ M_{\rm p} = 0.46 ^_~M_J$ transiting exoplanet with an orbital period of 4.35298 $\pm$ 0.00004 days. The transit has a depth of 9 mmag, and although our follow-up photometry does not allow us to constrain ...

Exoplanet transit photometry for stellar activity and exomoon research [PDF]

open access: yes, 2021
Photometry underlies important discoveries in observational astronomy, from the detection of stellar magnetic phenomena unveiling dynamic dynamo processes to the much sought-after identification of exomoons.

The exoplanet handbook [PDF]

open access: yes, 2018
With the discovery of planets beyond our solar system 25 years ago, exoplanet research has expanded dramatically, with new state-of-the-art ground-based and space-based missions dedicated to their discovery and characterisation.

The influence of galactic cosmic rays on ion-neutral hydrocarbon chemistry in the upper atmospheres of free-floating exoplanets [PDF]

open access: yes, 2014
The authors highlight financial support of the European Community under the FP7 by an ERC starting grant.Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry.

A Giant Impact as the Likely Origin of Different Twins in the Kepler-107 Exoplanet System [PDF]

open access: yes, 2019
Measures of exoplanet bulk densities indicate that small exoplanets with radius less than 3 Earth radii (R(sub )) range from low-density sub-Neptunes containing volatile elements to higher-density rocky planets with Earth-like or iron-rich (Mercury-like)

Exoplanet clouds [PDF]

open access: yes, 2019
Clouds, which are common features in Earth's atmosphere, form in atmospheres of planets that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet atmospheres can be chemically extremely rich.

Spatial distribution of exoplanet candidates based on [PDF]

open access: yes, 2020
Context. Surveying the spatial distribution of exoplanets in the Galaxy is important for improving our understanding of planet formation and evolution. Aims. We aim to determine the spatial gradients of exoplanet occurrence in the Solar neighbourhood and
