Long-term monitoring of WASP-19 b: Signs of apsidal precession and molecular signatures

A. R. Rajkumar, A. Bayo, P. Peng +30

With more than 6000 exoplanets discovered so far, about 12 percent are hot Jupiters. Their large sizes and short orbital periods make them valuable targets for studying planetary f…

A search for transit timing variations in the transiting hot Jupiter systems HIP 65, NGTS-6, NGTS-10 and WASP-173

A. W. Griffiths, J. Southworth, L. Alegre +30

Hot Jupiters are Jupiter-mass planets with orbital periods of less than ten days. Their short orbital separations make tidal dissipation within the stellar host especially efficien…

The Orbit of WASP-4 b is in Decay

Ö. Baştürk, A. C. Kutluay, A. Barker +25

WASP-4 b is a hot Jupiter exhibiting a decreasing orbital period, prompting investigations into potential mechanisms driving its evolution. We analyzed 173 transit light curves, in…

OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host

M. J. Mróz, R. Poleski, A. Udalski +70

We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…

Gaia21blx: Complete resolution of a binary microlensing event in the Galactic disk

P. Rota, V. Bozza, M. Hundertmark +22

Context. Gravitational microlensing is a method that is used to discover planet-hosting systems at distances of several kiloparsec in the Galactic disk and bulge. We present the an…
