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…
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…
SPECTRUMMATE: A Low-cost Spectrometer for Small Telescopes
Hien Phan-Thanh, Nguyen Nguyen-Duc, Thuy Le-Quang +2
This project presents the development and implementation of a compact spectrometer, named SPECTRUMMATE, tailored for small telescopes. Small telescopes offer several advantages: th…
Broadband Low-Resolution Spectrograph - SpectrumMate LR
Nguyen Nguyen-Duc, Thuy Le-Quang, Tobias C. Hinse +2
This paper presents the development and application of SpectrumMate LR, a broadband, low-resolution spectrograph for small telescope use. SpectrumMate LR is designed to offer affor…
