Solution of newly observed transit of the exoplanet HAT-P-24b: no TTV and TDV signals

Original · EN

We present photometric observations of transit of the exoplanet HAT-P-24b using the Rozhen 2 m telescope. Its solution gives relative stellar radius rₛ=0.1304 (a/Rₛ=7.669), relative planet radius rₚ=0.01304 and orbital inclination of 90 degree. The calculated planet radius is Rₚ=1.316 Rⱼ and corresponds to planet density of rhoₚ=0.37 g cm⁻³. Our parameter values are between those of the previous two solutions. We did not find evidences of TTV and TDV signals of HAT-P-24b.
