Abstract:
I measure the physical properties of 38 transiting extrasolar
planetary systems, bringing the total number studied within the
Homogeneous Studies project to 82. Transit light curves are modelled
using the jktebop code, with careful attention paid to limb darkening,
orbital eccentricity and contaminating light. The physical properties
of each system are obtained from the photometric parameters, published
spectroscopic measurements and five sets of theoretical stellar model
predictions. Statistical errors are assessed using Monte Carlo and
residual permutation algorithms and propagated via a perturbation
algorithm. Systematic errors are estimated from the interagreement
between results calculated using five theoretical stellar models. I
present the first results based on Kepler short-cadence data for
Kepler-14, Kepler-15 and KOI-135.
