UBV(RI)C photometry of transiting planet hosting stars [PDF]
We present new UBV(RI)_C photometry of 22 stars that host transiting planets, 19 of which were discovered by the WASP survey. We use these data together with 2MASS JHK_S photometry to estimate the effective temperature of these stars using the infrared flux method. We find that the effective temperature estimates for stars discovered by the WASP survey

DETECTING THE WIND-DRIVEN SHAPES OF EXTRASOLAR GIANT PLANETS FROM TRANSIT PHOTOMETRY [PDF]
Several processes can cause the shape of an extrasolar giant planet's shadow, as viewed in transit, to depart from circular. In addition to rotational effects, cloud formation, non-homogenous haze production and movement, and dynamical effects (winds ...

Optimized transit detection algorithm to search for periodic transits of small planets [PDF]
We present a new method to detect planetary transits from time-series photometry, the transit least squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar limb darkening and planetary ingress and egress into account.

Transit timing of TrES-2: a combined analysis of ground- and space-based photometry [PDF]
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which offer the matchless possibility to combine long-term ground-based ...

A hot Uranus transiting the nearby M dwarf GJ 3470 - Detected with HARPS velocimetry. Captured in transit with TRAPPIST photometry [PDF]
We report on the discovery of GJ 3470 b, a transiting hot Uranus of mass mp = 14.0 ± 1.8 M⊕, radius Rp = 4.2 ± 0.6 R⊕ and period P = 3.3371 ± 0.0002 day. Its host star is a nearby (d = 25.2 ± 2.9 pc) M1.5 dwarf of mass M⋆ = 0.54 ± 0.07 M⊙ and radius R⋆ =

The stellar variability noise floor for transiting exoplanet photometry with PLATO [PDF]
ABSTRACT One of the main science motivations for the ESA PLAnetary Transit and Oscillations (PLATO) mission is to measure exoplanet transit radii with 3 per cent precision. In addition to flares and starspots, stellar oscillations and granulation will enforce fundamental noise floors for transiting exoplanet radius measurements.

MOST SPACE TELESCOPE PHOTOMETRY OF THE 2010 JANUARY TRANSIT OF EXTRASOLAR PLANET HD80606b [PDF]
We present observations of the full 2010 January transit of HD80606b from the Canadian microsatellite, Microvariability and Oscillations of Stars. By employing a space-based telescope, we monitor the entire transit, thus limiting systematic errors that ...
