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.

NEAR-INFRARED TRANSIT PHOTOMETRY OF THE EXOPLANET HD 149026b [PDF]
The Astrophysical Journal, 2009 The transiting exoplanet HD 149026b is an important case for theories of planet formation and planetary structure, because the planet's relatively small size has been interpreted as evidence for a highly metal-enriched composition. We present observations of 4 transits with the Near Infrared Camera and Multi-Object Spectrometer on the Hubble Space ...

Observations of planetary transits at the University Observatory Jena
EPJ Web of Conferences, 2011 We report on observations of transit events of the transiting planets XO-1b, TrES-1 and TrES-2 with a 25 cm telescope of the University Observatory Jena.

Transit Photometry as an Exoplanet Discovery Method [PDF]
, 2018 Photometry with the transit method has arguably been the most successful exoplanet discovery method to date. A short overview about the rise of that method to its present status is given. The method's strength is the rich set of parameters that can be obtained from transiting planets, in particular in combination with radial velocity observations; the ...

Feasibility of transit photometry of nearby debris discs [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Dust in debris discs is constantly replenished by collisions between larger objects. In this paper, we investigate a method to detect these collisions. We generate models based on recent results on the Fomalhaut debris disc, where we simulate a background star transiting behind the disc, due to the proper motion of Fomalhaut.

The Astronomical Journal, 2023 Never before has the detection and characterization of exoplanets via transit photometry been as promising and feasible as it is now, due to the increasing breadth and sensitivity of time domain optical surveys.

The Planetary Science Journal, 2021 We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N -body dynamical analysis of the seven-planet system using ...

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.

Precision photometry for planetary transits
, 2007 We review the state of the art in follow-up photometry for planetary transit searches. Three topics are discussed: (1) Photometric monitoring of planets discovered by radial velocity to detect possible transits (2) Follow-up photometry of candidates from photometric transit searches to weed out eclipsing binaries and false positives (3) High-precision ...
