When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around...

Planet formation is generally described in terms of a system containing the host star and a protoplanetary disk, of which the internal properties (for example, mass and...

The detection of a dust disk around the white dwarf star G29-38 and transits from debris orbiting the white dwarf WD 1145+017 confirmed that the photospheric trace metals found...

We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT space mission, which have been obtained from ground-based observations since the mission's...

We present the latest results of an ongoing multiplicity survey of exoplanet hosts, which was initiated at the Astrophysical Institute and University Observatory Jena, using...

The CHaracterising ExOPlanet Satellite (CHEOPS) was selected on October 19, 2012, as the first small mission (S-mission) in the ESA Science Programme and successfully launched...

Eccentric giant planets are predicted to have acquired their eccentricity through two major mechanisms: the Kozai-Lidov effect or planet-planet scattering, but it is normally...

We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star (V=9.7mag) discovered by the TESS...

We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 (M=1.17M_{sun}_, R=1.31R_{sun}) star, which hosts a transiting planet recently...

The Transiting Exoplanet Survey Satellite (TESS) mission has provided the community with high-precision times series photometry for ~2.8 million stars across the entire sky via...

We present TransitFit, a package designed to fit exoplanetary transit light-curves. TransitFit offers multi-epoch, multi-wavelength fitting of multi-telescope transit data....

We conduct a survey, which explores the data releases of the ESA-Gaia mission, in order to investigate the multiplicity of exoplanet hosts at distances of less than 625pc around...

Hot Jupiters have been perceived as loners devoid of planetary companions in close orbital proximity. However, recent discoveries based on space-borne precise photometry have...

We report the discovery of two warm sub-Neptunes transiting the bright (G=9.5mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet...

HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright (G=9.0mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of 3.9+/-0.044...

We have performed low-resolution ground-based spectroscopy of HATS-46 b in transmission, using the EFOSC2 instrument on the ESO New Technology Telescope (NTT). HATS-46 b is a...

With over 5000 exoplanets currently detected, there is a need for a primary classification method to prioritise candidates for biosignature observations. Here, we develop a...

We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 days,...

Here we present an initial look at the dynamics and stability of 178 multiplanetary systems which are already confirmed and listed in the NASA Exoplanet Archive. To distinguish...

The cross-correlation function and template matching techniques have dominated the world of precision radial velocities for many years. Recently, a new technique, named...
