Photodynamical analysis of the nearly resonant planetary system WASP-148. Accurate transit-timing variations and mutual orbital inclination [PDF]
Astronomy & Astrophysics, 2022 WASP-148 is a recently announced extra-solar system harbouring at least two giant planets. The inner planet transits its host star. The planets travel on eccentric orbits and are near the 4:1 mean-motion resonance, which implies significant mutual ...

The effects of star spots on transit photometry [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWe have undertaken an observational program to photometrically monitor several transiting planet host stars. The Rabus et al. result for TrES-1 showed the dramatic effects star spots can have on transit photometry. We will investigate the effects of spots on transit light curves and estimates of planetary radii.

Non-detection of Contamination by Stellar Activity in the Spitzer Transit Light Curves of TRAPPIST-1 [PDF]
, 2018 We apply the transit light curve self-contamination technique of Morris et al. (2018) to search for the effect of stellar activity on the transits of the ultracool dwarf TRAPPIST-1 with 2018 Spitzer photometry.

No Conclusive Evidence for Transits of Proxima b in MOST Photometry [PDF]
The Astronomical Journal, 2017 Abstract The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be ...

Optical photometry of two transitional millisecond pulsars in the radio pulsar state [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We present ULTRACAM multiband optical photometry of two transitional millisecond pulsars (tMSPs), PSR J1023+0038 and PSR J1227−4853, taken while both were in their radio pulsar states. The light curves show significant asymmetry about the flux maxima in all observed bands, suggesting an asymmetric source of heating in the system.

Transit Depth Variations Reveal TOI-216 b to be a Super-puff
The Astronomical Journal, 2023 The planets of the TOI-216 system have been previously observed to exhibit large transit-timing variations, which enabled precise mass characterization of both transiting planets.

Differential rotation of Kepler-71 via transit photometry mapping of faculae and starspots
Monthly notices of the Royal Astronomical Society, 2019 Knowledge of dynamo evolution in solar-type stars is limited by the difficulty of using active region monitoring to measure stellar differential rotation, a key probe of stellar dynamo physics.
