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...

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...

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...

A total of 3350 objects from the Sixth Catalog of Orbits of Visual Binary Stars (ORB6) are investigated to validate Gaia Early Data Release 3 (EDR3) parallaxes and provide mass...

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...

CHEOPS (CHaracterising ExOPlanet Satellite) is an ESA S-class mission that observes bright stars at high cadence from low-Earth orbit. The main aim of the mission is to...

We present results of the comparative analysis of the two wide binary systems - 16 Cyg, with a giant gas planet orbiting around 16 Cyg B, and HD 219542 without planet detected....

We aim to identify and characterise binary systems containing red supergiant (RSG) stars in the Small Magellanic Cloud (SMC) using a newly available ultraviolet (UV) point...

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...

We present a precise characterization of the TOI-561 planetary system obtained by combining previously published data with TESS and CHEOPS photometry, and a new set of 62...

We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in the Transiting Exoplanet...

From sector 1-44 TESS observations, 19 new rapidly oscillating Ap (roAp) stars, 103 ostensibly non-peculiar stars with roAp-like frequencies, and 617 {delta} Scuti stars with...

We present an optical transmission spectrum for WASP-94A b, the first atmospheric characterization of this highly-inflated hot Jupiter. The planet has a reported radius of...

Holczer, Mazeh, and collaborators (Holczer et al. 2016ApJS..225....9H, Cat. J/ApJS/225/9) used the Kepler 4-yr observations to derive a transit-timing catalog, identifying 260...

We present a comprehensive analysis of 10 years of HARPS radial velocities of the K2V dwarf star HD13808, which has previously been reported to host two unconfirmed planet...
