Earth, Venus, Mars and some extrasolar terrestrial planets1 have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. At...

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...

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...

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 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,...

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

We present new high-contrast images in near-infrared wavelengths ({lambda}c = 1.04, 1.24, 1.62, 2.18, and 3.78 um) of the young variable star CQ Tau, aiming to constrain the...

HATS-18 b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We...

The Transiting Exoplanet Survey Satellite (TESS) has detected thousands of exoplanet candidates since 2018, most of which have yet to be confirmed. A key step in the...

We study the transit timings of 10 exoplanets in order to investigate potential transit timing variations in them. We model their available ground-based light curves, some...
