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…

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…
