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 ...

Exoplanet characterization by multi-observatory transit photometry with TESS and CHEOPS [PDF]
, 2017 Space-based photometric surveys have discovered large numbers of planets transiting other stars, but these observe in a single band-pass and yield only the planet radius, orbital period, and transit duration.

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.

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.

Linearized Field Deblending: PSF Photometry for Impatient Astronomers [PDF]
, 2021 NASA's Kepler, K2 and TESS missions employ Simple Aperture Photometry (SAP) to derive time-series photometry, where an aperture is estimated for each star, and pixels containing each star are summed to create a single light curve. This method is simple, but in crowded fields the derived time-series can be highly contaminated.

High-resolution Imaging Transit Photometry of Kepler-13AB
Astronomical Journal, 2019 Using the high-resolution imaging instrument, ’Alopeke, at the Gemini-N telescope, we obtained simultaneous two-channel time-series observations of the binary exoplanet host star Kepler13-AB.
