Transit Timing Variations of the Sub-Saturn Exoplanet HAT-P-12b
Kaviya Parthasarathy, Hsin-Min Liu, Ing-Guey Jiang +12
We present Transit Timing Variations (TTVs) of HAT-P-12b, a low-density sub-Saturn mass planet orbiting a metal-poor K4 dwarf star. Using 14 years of observational data (2009-2022)…
