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…

Chasing the Tides: Searching for Orbital Decay Signatures in Transit Timing Data and Tidal Models for 20 Hot Jupiters

A. C. Kutluay, Ö. Baştürk, Adrian J. Barker +31

In this work, we present a transit timing variation analysis for 20 hot Jupiter systems, which we interpret with theoretical tidal dissipation models. For the majority of the sampl…

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…

AT2021uey: A planetary microlensing event outside the Galactic bulge

M. Ban, P. Voloshyn, R. Adomaviciene +42

We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF an…

Shape and spin state model of contact binary (388188) 2006 DP14 using combined radar and optical observations

Richard E. Cannon, Agata Rozek, Marina Brozović +36

Contact binaries are found throughout the solar system. The recent discovery of Selam, the satellite of MBA (152830) Dinkinesh, by the NASA LUCY mission has made it clear that the…
