The fates of planetary systems provide unassailable insights into their formation and
represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main …

Compared to the Earth, the exoplanet Kepler-78b has a similar size (1.2 R⊕) and an orbital
period a thousand times shorter (8.5 h). It is currently the smallest planet for which the mass …

The mass–period or radius–period distribution of close-in exoplanets shows a paucity of
intermediate mass/size (sub-Jovian) planets with periods≲ 3 d. We show that this sub …

Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly
shaped, aperiodic dips in flux of up to∼ 20 per cent. The dipping activity can last for …

ABSTRACT The Kepler Space Telescope is currently searching for planets transiting stars
along the ecliptic plane as part of its extended K2 mission. We processed the publicly …

We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b
obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

Age is a stellar parameter that is both fundamental and difficult to determine. Among middle-
aged M dwarfs, the most prolific hosts of close-in and detectable exoplanets, gyrochronology …

We present the detection and follow-up observations of planetary candidates around low-
mass stars observed by the K2 mission. Based on light-curve analysis, adaptive-optics …

We present 197 planet candidates discovered using data from the first year of the NASA K2
mission (Campaigns 0–4), along with the results of an intensive program of photometric …
