Measuring Exoplanetary Radii Using Transit Photometry
Journal of emerging investigators, 2019 The goal of this study was to measure the radii and constrain the orbital periods of three hot Jupiter exoplanets: HAT-P-25b, HAT-P-9b, and HAT-P-30b. Raw images of the host stars were acquired from the Apache Point Observatory in New Mexico.

HD 209458 planetary transits from Hipparcos photometry
, 2000 International audience; During its 39-month mission, Hipparcos observed the star HD 209458 on 89 occasions. Five of these observations are shown to correspond to epochs of planetary transits, with a 2.3±0.4% mean decrease of flux in the Hpband being observed during the transits. As a result of the long temporal baseline of more than 8 years between the

Transit observations at the observatory in Grossschwabhausen: XO-1b and TrES-1 [PDF]
, 2008 We report on observations of transit events of the transiting planets XO-1b and TrES-1 with the AIU Jena telescope in Grossschwabhausen. Based on our IR photometry (in March 2007) and available transit timings (SuperWASP, XO and TLC-project-data) we ...

TESS Timings of 31 Hot Jupiters with Ephemeris Uncertainties
The Astrophysical Journal Supplement Series, 2023 A precise transit ephemeris serves as the premise for follow-up exoplanet observations. We compare TESS Object of Interest (TOI) transit timings of 262 hot Jupiters with the archival ephemeris and find 31 of them having TOI timing offsets, among which ...

Spin-orbit misalignment in the HD80606 planetary system [PDF]
, 2009 We recently reported the photometric and spectroscopic detection of the primary transit of the 111-day-period, eccentric extra-solar planet HD80606 b, at Observatoire de Haute-Provence, France (Moutou et al. 2009). The whole egress of the primary transit

Time evolution and rotation of starspots on CoRoT-2 from the modelling of transit photometry [PDF]
, 2011 CoRoT-2, the second planet-hosting star discovered by the CoRoT satellite, is a young and active star. A total of 77 transits were observed for this system over a period of 135 days.

The Astronomical Journal, 2023 Previous studies of the exoplanet LTT 1445Ac concluded that the light curve from the Transiting Exoplanet Survey Satellite (TESS) was consistent with both grazing and nongrazing geometries. As a result, the radius and hence density of the planet remained
