HST/STIS Capability for Love Number Measurement of WASP-121b [PDF]

Astrophysical Journal, 2019
Data from transit light curves, radial velocity, and transit timing observations can be used to probe the interiors of exoplanets beyond the mean density, by measuring the Love numbers h2 and k2.

CHEOPS Performance for Exomoons: The Detectability of Exomoons by Using Optimal Decision Algorithm [PDF]

, 2015
Many attempts have already been made to detect exomoons around transiting exoplanets, but the first confirmed discovery is still pending. The experiences that have been gathered so far allow us to better optimize future space telescopes for this ...

Probing Transit Timing Variation and Its Possible Origin with 12 New Transits of TrES-3b [PDF]

Astronomical Journal, 2020
We present 12 new transit light curves of the hot-Jupiter TrES-3b observed during 2012−2018 to probe the transit timing variation (TTV). By combining the midtransit times determined from these 12 transit data with those reestimated through uniform ...

WASP-4 transit timing variation from a comprehensive set of 129 transits [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2020
We homogeneously reanalyse 124 transit light curves for the WASP-4 b hot Jupiter. This set involved new observations secured in 2019 and nearly all observations mentioned in the literature, including high-accuracy GEMINI/GMOS transmission spectroscopy ...

Analysis of Eclipsing Binary Stars and Identification of Exoplanets Using Transit Timing Variation Using data from TESS

Journal of Physics: Conference Series, 2022
This study uses openly available TESS (Transiting Exoplanet Sky Survey) data to detect evidence for potential exoplanet transits in an eclipsing binary system.

Transit timing variation signature of planet migration: the case of K2-24 [PDF]

Astronomy & Astrophysics, 2020
The convergent migration of two planets in a gaseous disc can lead to mean motion resonance (MMR) capture. In addition, pairs of planets in or near MMRs are known to produce strong transit timing variations (TTVs).

A dynamical analysis of the Kepler-11 planetary system [PDF]

, 2012
The Kepler-11 planetary system hosts at least six transiting super-Earth planets detected through the precise photometric observations of the Kepler mission (Lissauer et al.).

A Modified Kwee–Van Woerden Method for Eclipse Minimum Timing with Reliable Error Estimates

Galaxies, 2020
The Kwee–van Woerden (KvW) method used for the determination of eclipse minimum times has been a staple in eclipsing binary research for decades, due its simplicity and the independence of external input parameters, which also makes it well-suited to ...

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

The Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.
