The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

Mass and radius are two of the most fundamental properties of an astronomical object.
Increasingly, new planet discoveries are being announced with a measurement of one of …

We carried out a Bayesian homogeneous determination of the orbital parameters of 231
transiting giant planets (TGPs) that are alone or have distant companions; we employed …

Context. High-precision determinations of abundances of elements in the atmospheres of
the Sun and solar twin stars indicate that the Sun has an unusually low ratio between …

Abstract Observing the Rossiter–McLaughlin effect during a planetary transit allows the
determination of the angle λ between the sky projections of the star's spin axis and the …

The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

We present a grid of forward model transmission spectra, adopting an isothermal
temperature-pressure profile, alongside corresponding equilibrium chemical abundances …

Celestial bodies with a mass of» MM 10 Jup have been found orbiting nearby stars. It is
unknown whether these objects formed like gas-giant planets through core accretion or like …

The spin–orbit angle, or obliquity, is a powerful observational marker that allows us to
access the dynamical history of exoplanetary systems. For this study, we have examined the …

Context. Exoplanets have now been proven to be very common. The number of its
detections continues to grow following the development of better instruments and missions …
