A Search for the Transit of HD 168443b: Improved Orbital Parameters and Photometry [PDF]

The Astrophysical Journal, 2011
The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. In this work we present the search for transits of HD 168443b, a massive planet orbiting the bright star HD 168443 ...

Precision photometry for planetary transits [PDF]

arXiv, 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 ...

The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry [PDF]

, 2007
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.

Characterization of transiting exoplanets by way of differential photometry [PDF]

Physics Education. 49(3),p.293 (2014), 2015
This paper describes a simple activity for plotting and characterizing the light curve from an exoplanet transit event by way of differential photometry analysis. Using free digital imaging software, participants analyse a series of telescope images with the goal of calculating various exoplanet parameters, including its size, orbital radius and ...

Transit Analysis Package: An IDL Graphical User Interface for Exoplanet Transit Photometry [PDF]

Advances in Astronomy, 2012
We present an IDL graphical user-interface-driven software package designed for the analysis of exoplanet transit light curves. The Transit Analysis Package (TAP) software uses Markov Chain Monte Carlo (MCMC) techniques to fit light curves using the ...

TERMS Photometry of Known Transiting Exoplanets [PDF]

The Astronomical Journal, 2011
The Transit Ephemeris Refinement and Monitoring Survey (TERMS) conducts radial velocity and photometric monitoring of known exoplanets in order to refine planetary orbits and predictions of possible transit times.

CHEOPS: A transit photometry mission for ESA's small mission programme [PDF]

EPJ Web of Conferences, 2013
Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright ...

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.

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.

Non-detection of previously reported transits of HD 97658b with MOST photometry [PDF]

The Astrophysical Journal, 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 ...
