Starspots are created by local magnetic fields on the surfaces of stars, just as sunspots.
Their fields are strong enough to suppress the overturning convective motion and thus block …

We provide an overview of stellar variability in the first quarter data from the Kepler mission.
The intent of this paper is to examine the entire sample of over 150,000 target stars for …

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 …

We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

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 …

I calculate the physical properties of 32 transiting extrasolar planet and brown-dwarf systems
from existing photometric observations and measured spectroscopic parameters. The …

Until recently, infrared observations of exoplanetary atmospheres have typically been
interpreted using models that assumed solar elemental abundances. With the chemical …

Aims. We report the discovery of very shallow (), periodic dips in the light curve of an active
G9V star observed by the CoRoT satellite, which we interpret as caused by a transiting …

We measure the mass of a modestly irradiated giant planet, KOI-94d. We wish to determine
whether this planet, which is in a 22 day orbit and receives 2700 times as much incident flux …

Context. Several competing scenarios for planetary-system formation and evolution seek to
explain how hot Jupiters came to be so close to their parent stars. Most planetary …
