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 ...

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 ...

Comet C/2011 J2 (LINEAR): Photometry and stellar transit [PDF]
Planetary and Space Science, 2016 We present results of two-year photometric monitoring of Comet C/2011 J2 (LINEAR) that spans the time period from February 2013 through December 2014, before and after perihelion passage. The observations were conducted with broadband R filter. Analysis of observations of Comet C/2011 J2 (LINEAR) allows estimating the nucleus radius as function of ...

Millimagnitude Optical Photometry for the Transiting Planetary Candidate OGLE‐TR‐109 [PDF]
The Astrophysical Journal, 2006 We present precise V-band photometry for the low-amplitude transit candidate star OGLE-TR-109. This is an extreme case among the transiting candidates found by the OGLE group because of the early spectral type of the star (F0V), of the low transit amplitude (A_I=0.008 mag), and of the very short period (P=0.58909 days) of the orbiting companion.

Relative photometry of transiting exoplanet CoRoT-Exo-2b
, 2009 Relative CCD photometry of the extrasolar planet COROT-Exo-2b transiting in front of its parent star was carried out at the Astronomical and Geophysical Observatory of Comenius University at Modra (AGO). Physical and orbital parameters were determined and compared with the previous published data.

Exoplanet characterization by multi-observatory transit photometry with TESS and CHEOPS [PDF]
Monthly Notices of the Royal Astronomical Society, 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. Information on the masses, compositions, and any atmospheres of these planets requires additional observations from the ground or space.

Unveiling an exoplanetary Neptunian atmosphere through multiband transit photometry [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractThe “effective” radius of a planet is a function of wavelength due to scattering and/or absorption processes, and we can exploit simultaneous multiband transit photometry to probe the atmospheric scale height and composition. We present new photometric data of the recently discovered “hot Uranus” GJ3470b, gathered with the LBC camera at LBT ...

Transit and secondary eclipse photometry in the near-infrared
, 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.

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 ...
