Diffuse and specular brightness models applied to LEO satellites. Case study: The ONEWEB constellation
MarÃa Romero-Colmenares, Katherine Vieira, Jeremy Tregloan-Reed +11
Context. To better understand the observed brightness of low Earth orbit satellites, we must characterize their reflectivity, which in turn depends importantly on their bus designs…
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…
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…
