Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Åukasz Wyrzykowski, PrzemysÅaw J. MikoÅajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
Chasing the Tides: Searching for Orbital Decay Signatures in Transit Timing Data and Tidal Models for 20 Hot Jupiters
A. C. Kutluay, Ã. BaÅtürk, 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
Ã. BaÅtürk, 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…
TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
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…
