System parameters, transit times and secondary eclipse constraints of the exoplanet systems HAT-P-4, TrES-2, TrES-3 and WASP-3 from the NASA EPOXI Mission of Opportunity
planetary systems — eclipses — stars individual (HAT-P-4
2010/11/12
As part of the NASA EPOXI Mission of Opportunity, we observed seven known transiting extrasolar planet systems in order to construct time series photometry of extremely high phase coverage and precisi...
Modeling of the spectral energy distribution of the cataclysmic variable TT Ari and evaluation of the system parameters
Solar and Stellar Astrophysics (astro-ph.SR)
