We present a new generation of substellar atmosphere and evolution models, appropriate
for application to studies of L-, T-, and Y-type brown dwarfs and self-luminous extrasolar …

Abstract We describe the Next Generation Transit Survey (NGTS), which is a ground-based
project searching for transiting exoplanets orbiting bright stars. NGTS builds on the legacy of …

Accurately measuring stellar parameters is a key goal to increase our understanding of the
observable Universe. However, current methods are limited by many factors, in particular …

M dwarfs remain active over longer timescales than their Sunlike counterparts, with
potentially devastating implications for the atmospheres of their planets. However, the age at …

Abstract The Upper Scorpius OB association is the nearest region of recent massive star
formation and thus an important benchmark for investigations concerning stellar evolution …

We have created an up-to-date catalogue of 214 brown dwarfs (BDs) in binaries with P< 104
d. This allows us to examine the population statistics of the BD desert. We searched Gaia …

We present allesfitter, a public and open-source Python software for flexible and robust
inference of stars and exoplanets given photometric and radial velocity data. Allesfitter offers …

We present the discovery of NGTS-1b, a hot Jupiter transiting an early M-dwarf host (T eff,*=
K) in a P= 2.647 d orbit discovered as part of the Next Generation Transit Survey (NGTS) …

Aims. Our scientific goal is to provide revised membership lists of the α Per, Pleiades, and
Praesepe clusters exploiting the second data release of Gaia and produce five-dimensional …

We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th
magnitude K-dwarf in a 1.34 d orbit. NGTS-4b has a mass M= 20.6±3.0 M⊕ and radius R …
