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 …

A knowledge of stellar ages is crucial for our understanding of many astrophysical
phenomena, and yet ages can be difficult to determine. As they become older, stars lose …

Magnetic activity is a ubiquitous feature of stars with convective outer layers, with
implications from stellar evolution to planetary atmospheres. Investigating the mechanisms …

Variability in the light curves of spotted, rotating stars is often non-sinusoidal and quasi-
periodic–spots move on the stellar surface and have finite lifetimes, causing stellar flux …

Slow Rotators in the Hyades and Praesepe - IOPscience Skip to content IOP Science home …

While the mission's primary goal was focused on exoplanet detection and characterization,
Kepler made and continues to make extraordinary advances in stellar physics. Stellar …

Aims. The main objective of this project is to characterise chromospheric activity of FGK stars
from the HARPS archive. We start, in this first paper, by presenting a catalogue of …

We present a new age-dating technique that combines gyrochronology with isochrone fitting
to infer ages for FGKM main-sequence and subgiant field stars. Gyrochronology and …

Gaia and Kepler - IOPscience Skip to content IOP Science home Accessibility Help Search all …

Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits,
and structures are shaped by their environment. Young planets (< 1 Gyr) offer an opportunity …
