The Transit Timing and Transmission Spectrum of Hot Jupiter WASP-43 b from a decade of Multi-band Transit Follow-up Observations

Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +21

We present a new set of 35 transit light curves of the hot Jupiter WASP-43~b, obtained through the SPEARNET network. These datasets were analyzed together with previously published…

Investigation of Transit Timing and an Optical Transmission Spectrum of the Hot Jupiter WASP-11 b

Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +15

WASP-11~b/HAT-P-10~b is an inflated hot Jupiter, which has a low density that makes it a good target for atmospheric studies using the transmission spectroscopy technique. In this…

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…

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…

Transit Timing Variation of K2-237b: Hints Toward Planet Disk Migration

Fan Yang, Richard J. Long, Eamonn Kerins +8

Hot Jupiters should initially form at considerable distances from host stars and subsequently migrate towards inner regions, supported directly by transit timing variation (TTV). W…
