The transiting system GJ1214: high-precision defocused transit observations and a search for evidence of transit timing variation (2012)
Journal Article
Harpsøe, K. B. W., Hardis, S., Hinse, T. C., Jørgensen, U. G., Mancini, L., Southworth, J., …Wertz, O. (2013). The transiting system GJ1214: high-precision defocused transit observations and a search for evidence of transit timing variation. Astronomy & Astrophysics, 549, Article A10. https://doi.org/10.1051/0004-6361/201219996Aims. We present 11 high-precision photometric transitobservations of the transiting super-Earth planet GJ 1214 b. Combining these data with observations from other authors, we investigate the ephemeris for possible signs of transit timing variations...

Transits and starspots in the WASP-19 planetary system (2012)
Journal Article
Tregloan-Reed, J., Southworth, J., & Tappert, C. (2013). Transits and starspots in the WASP-19 planetary system. Monthly Notices of the Royal Astronomical Society, 428(4), 3671-3679. https://doi.org/10.1093/mnras/sts306We have developed a new model for analysing light curves of planetary transits when there are starspots on the stellar disc. Because the parameter space contains a profusion of local minima we developed a new optimization algorithm which combines the...

Spitzer 3.6 and 4.5 mu m full-orbit light curves of WASP-18 (2012)
Journal Article

Monthly Notices of the Royal Astronomical Society, 428(3), 2645-2660. https://doi.org/10.1093/mnras/sts231We present new lightcurves of the massive hot Jupiter system WASP-18 obtained with the Spitzer spacecraft covering the entire orbit at 3.6 micron and 4.5 micron. These lightcurves are used to measure the amplitude, shape and phase of the thermal phas... Read More about Spitzer 3.6 and 4.5 mu m full-orbit light curves of WASP-18.
WASP-78b and WASP-79b: Two highly-bloated hot Jupiter-mass exoplanets orbiting F-type stars in Eridanus (2012)
Journal Article

Astronomy and Astrophysics, 547, Article A61. https://doi.org/10.1051/0004-6361/201219731We report the discovery of WASP-78b and WASP-79b, two highly-bloated Jupiter-mass exoplanets orbiting F-type host stars. WASP-78b orbits its V=12.0 host star (TYC 5889-271-1) every 2.175 days and WASP-79b orbits its V=10.1 host star (CD-30 1812) ever...

Southworth, J. (2012). HSTEP -- Homogeneous Studies of Transiting Extrasolar Planets. . https://doi.org/10.1017/S174392131301332XI give a summary of the HSTEP project: an effort to calculate the physical properties of the known transiting extrasolar planets using a homogeneous approach. I discuss the motivation for the project, list the 83 planets which have already been studi... Read More about HSTEP -- Homogeneous Studies of Transiting Extrasolar Planets.
Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics (2012)
Conference Proceeding
Taylor. (2012). Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics. In Proceedings of the workshop "Orbital Couples: Pas de Deux in the Solar System and the Milky Way" (51-58)Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities,...
