The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry [PDF]
, 2006 Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. Here we report new high-accuracy photometry of the transits of OGLE-TR-10 and OGLE-TR-56 with VLT/FORS1.

Near-ultraviolet transit photometry of HAT-P-32 b with the Large Binocular Telescope: Silicate aerosols in the planetary atmosphere [PDF]
, 2017 Broad-band exoplanet transit photometry can characterize the planetary atmosphere when observed at multiple selected filters. This observing technique can reveal gradients in the spectra of extrasolar planets, for example, the slope of decreasing opacity

Transit origami: a method to coherently fold exomoon transits in time series photometry [PDF]
Monthly notices of the Royal Astronomical Society, 2021 One of the simplest ways to identify an exoplanetary transit is to phase fold a photometric time series upon a trial period – leading to a coherent stack when using the correct value. Such phase-folded transits have become a standard data visualization

Effective temperatures and radii of planet-hosting stars from IR photometry [PDF]
Astron.Astrophys. 411 (2003) L501-L504, 2003 In this paper we present and analyse determinations of effective temperatures of planet-hosting stars using infrared (IR) photometry. One of our goals is the comparison with spectroscopic temperatures to evaluate the presence of systematic effects that could alter the determination of metal abundances.

Multilayer modeling of the aureole photometry during the Venus transit: comparison between SDO/HMI and VEx/SOIR data [PDF]
, 2016 The mesosphere of Venus is a critical range of altitudes in which complex temperature variability has been extensively studied by the space mission Venus Express (Vex) during its eight-years mission (2006-2014).

Transit and secondary eclipse photometry in the near-infrared [PDF]
arXiv, 2007 Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 micron.

The Transit Light Curve Project. IV. Five Transits of the Exoplanet OGLE-TR-10b [PDF]
, 2005 We present I and B photometry of five distinct transits of the exoplanet OGLE-TR-10b. By modeling the light curves, we find the planetary radius to be R_P = 1.06 +/- 0.08 R_Jup and the stellar radius to be R_S = 1.10 +/- 0.07 R_sun. The uncertainties are dominated by statistical errors in the photometry.

Non-detection of previously reported transits of HD 97658b with MOST photometry [PDF]
, 2012 The radial velocity-discovered exoplanet HD 97658b was recently announced to transit, with a derived planetary radius of 2.93 \pm 0.28 R_{Earth}. As a transiting super-Earth orbiting a bright star, this planet would make an attractive candidate for ...
