Revisiting the Orbital Dynamics of the Hot Jupiter WASP-12 b with New Transit Times

Shraddha Biswas, Ing-Guey Jiang, Li-Chin Yeh +10

In this study, we examine the transit timing deviations of the extensively studied hot Jupiter WASP-12 b using a comprehensive dataset of 391 transit light curves. The dataset incl…

A decade of transit photometry for K2-19: Revised system architecture

J. M. Almenara, R. Mardling, A. Leleu +21

The star K2-19 hosts a pair of Neptunian planets deep inside the 3:2 resonance. They induce strong transit-timing variations with two incommensurate frequencies. Previous photodyna…

Investigating Transit Timing Variations in the Ultra-short Period Exoplanet WASP-19b

Shraddha Biswas, Ing-Guey Jiang, Li-Chin Yeh +6

In this study, we present a comprehensive analysis of transit timing variations (TTVs) in the ultra-short-period gas giant WASP-19b, which orbits a G-type main-sequence star. Our a…

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)…

Towards High Precision Mass Measurements of Two Sub-Neptunes in the K2-266 Planetary System Through Transit Timing

Ing-Guey Jiang, Li-Chin Yeh, Billy Edwards +3

Sub-Neptunes have been found to be one of the most common types of exoplanets, yet their physical parameters and properties are poorly determined and in need of further investigati…
