Scintillation Noise in Exoplanet Transit Photometry
Journal of Physics: Conference Series, 2015 Transit photometry is a powerful technique for studying exoplanets. Transit observations from the ground of targets of magnitude V= 10 or brighter, however, are limited by scintillation noise due to Earth's atmosphere.

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 ...

High-resolution Imaging Transit Photometry of Kepler-13AB [PDF]
The 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.

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.

HST/FGS Photometry of Planetary Transits of HD 209458 [PDF]
AIP Conference Proceedings, 2004 We present the data, and modeling and analysis results from the photometric monitoring of five planetary transits of HD 209458 using the Fine Guidance Sensors (FGS) onboard the Hubble Space Telescope (HST). We have now included the output from all four FGS photometers in our data reduction and analysis increasing our S/N over our previous results.

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 Photometry of the Core-dominated Planet HD 149026b [PDF]
The Astrophysical Journal, 2005 We report g, V, and r photometric time series of HD 149026 spanning predicted times of transit of the Saturn-mass planetary companion, which was recently discovered by Sato and collaborators.

IRSF SIRIUS JHKs Simultaneous Transit Photometry of GJ1214b [PDF]
Publications of the Astronomical Society of Japan, 2012 We report high precision transit photometry of GJ1214b in JHKs bands taken simultaneously with the SIRIUS camera on the IRSF 1.4m telescope at Sutherland, South Africa.

ECCENTRICITY FROM TRANSIT PHOTOMETRY: SMALL PLANETS IN KEPLER MULTI-PLANET SYSTEMS HAVE LOW ECCENTRICITIES [PDF]
, 2015 Solar system planets move on almost circular orbits. In strong contrast, many massive gas giant exoplanets travel on highly elliptical orbits, whereas the shape of the orbits of smaller, more terrestrial, exoplanets remained largely elusive.

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 ...
