Transit timing variations (TTVs) can provide useful information on compact multi-planetary systems observed by transits by setting constraints on the masses and eccentricities...

The current architecture of a given multi-planetary system is a key fingerprint of its past formation and dynamical evolution history. Long-term follow-up observations are key...

Recent studies based on photometry from the Transiting Exoplanet Survey Satellite (TESS) have suggested that the dayside of KELT-1b, a strongly irradiated brown dwarf, is...

We report periodic oscillations in the 15-year-long optical light curve of the gravitationally lensed quasar J0158-4325 at z_s_=1.29. The signal is enhanced during a high...

We report the discovery of a 1.32^+0.10^-0.10_M_Jup planet orbiting on a 75.12 day period around the G3V 10.8^+2.1^-3.6_Gyr old star TOI-5542 (TIC 466206508; TYC 9086-1210-1)....

Observations of the phase curves and secondary eclipses of extrasolar planets provide a window on the composition and thermal structure of the planetary atmospheres. For...

The HD 108236 system was first announced with the detection of four small planets based on TESS data. Shortly after, the transit of an additional planet with a period of 29.54d...

In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching...

CzeV343 (=V849 Aur) was previously identified as a candidate double eclipsing binary (2+2 quadruple), where the orbital periods of the two eclipsing binaries (P_A_~1.2-days and...

We present the discovery of two small planets transiting HD 93963A (TOI-1797), a GOV star (M=1.109+/-0.043M_{sun}_, R = 1.043+/-0.009R_{sun}) in a visual binary system. We...

We present photometric and spectroscopic observations of the Type IIn supernova SN 2019zrk (a.k.a. ZTF 20aacbyec). The SN shows a >~100 day precursor, with a slow rise,...

The detection of the first exoplanet paved the way for the era of transit-photometry space missions with revolutionary photometric precision, whose aim is to discover new...

Ultra-hot Jupiters (UHJs), rendering the hottest planetary atmospheres, offer great opportunities of detailed characterisation with high-resolution spectroscopy. The extremely...

Long-period transiting planets provide the opportunity to better understand the formation and evolution of planetary systems. Their atmospheric properties remain largely...

Statistical analyses based on Kepler data show that most of the early-type M dwarfs host multi-planet systems consisting of Earth to sub-Neptune sized planets with orbital...

We report the discovery and characterization of two small transiting planets orbiting the bright M3.0 V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in...

Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as the hottest planet thus far discovered with a dayside temperature of over 4500K....

Great strides have been made in recent years in the understanding of the mechanisms involved in the formation and evolution of planetary systems; despite this, many...

The measurement of the spin-orbit alignment of hot Jupiters, with a range of orbital and physical properties, can provide information about the evolution of the orbits of this...

TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G=8.9mag), young (340+/-80Myr) K-type star. Although a validated planetary system, the orbits of...
