PARAMETERS OF RECENT TRANSITS OF HAT-P-23b
Four transits of the exoplanet HAT-P-23b were recently observed with the 0.36 m telescope at the Universidad de Monterrey Observatory. The four light curves were successfully combined to obtain a resulting one with reduced scat- tering per bin. This curve was modeled using a Monte Carlo method to ob...

| Resumo: | Four transits of the exoplanet HAT-P-23b were recently observed with the 0.36 m telescope at the Universidad de Monterrey Observatory. The four light curves were successfully combined to obtain a resulting one with reduced scat- tering per bin. This curve was modeled using a Monte Carlo method to obtain the essential parameters that characterize the system. Assuming orbital param- eters such as eccentricity e and longitude of periastron ! from the discovery pa- per, we found values of Rp/R* = 0.1105+0.0015 −0.0013 for the planet-to-star radius ra- tio, a/R* = 4.23+0.06 −0.12 for the scaled semimajor axis, and an orbital inclination of the system of i = 87.9?+1.5 −2.2. We also derive an improved orbital period of 1.2128868 ± 0.0000004 days (To = 2, 454, 852.26542 ± 0.00018 BJD TDB) for the system. |
