J-PAS (Javalambre-PAU Astrophysical Survey) is a Spanish-Brazilian collaboration to conduct an innovative photometric survey of more than 8000 square degrees of northern sky using a system of 57 filters, 54 narrow-band (FWHM=13.8 nm) filters continuously populating the spectrum between 370 to 920 nm with 10.0 nm steps, plus 3 broad-band filters

Detection of planets in the habitable zone is one of the key drivers of the exoplanet science community. We present a detailed strategy for such detection around L and T dwarfs. We plan to implement the outcome of the analysis as a transit survey to search for planets around known L and T dwarfs. Understanding of the variability of these cool

With a mass of 7.4 Earth masses and radius of 1.6 Earth radii, CoRoT-7b is among the smallest transiting planets found to date. Due to its small size, the transit signal is very shallow, which makes the estimation of the planetary parameters from the light curve challenging. We carry out a Bayesian analysis of the CoRoT-7b lightcurve using a

Aims: Using the CoRoT space based photometry of the O-type binary HD 46149, stellar atmospheric effects related to rotation can be separated from pulsations, because they leave distinct signatures in the light curve. This offers the possibility of characterising and exploiting any pulsations seismologically. Methods: Combining high-quality space

Planets forming around close binary systems should form in the binary orbital plane (varying precession periods of protoplanetary material should provide strong collisional damping; Schneider and Doyle 1995). Planets around eclipsing binaries may then be expected to have formed in the binary orbital plane and thus to be detected by their transits

We present near-infrared colour-magnitude diagrams and star counts for a number of regions along the Galactic plane. It is shown that along the l=27°, b=0° line of sight there is a feature at 5.7+/-0.7kpc with a density of stars at least a factor of 2 and probably more than a factor of 5 times that of the disc at the same position. This feature
