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

TESS and HARPS-N Unveil Two Planets Transiting TOI-1453. A Super-Earth and One of the Lowest Mass sub-Neptunes
We report on the validation and characterisation of two transiting planets around TOI-1453, a K-dwarf star in the TESS northern continuous viewing zone. In addition to the TESS data, we […]

Statistical Reevaluation of the USP Classification Boundary: Smaller Planets Within 1 Day, Larger Period Ratios Below 2 Days
Terrestrial worlds with P<1 day, known as ultra-short period planets (USPs), comprise a physically distinct population whose origins may be attributed to various possible formation channels within multi-planet systems.

KOBE 1: The First Planetary System From the KOBE survey. Two Planets Likely Residing in the sub-Neptune Mass Regime Around a Late K-dwarf
K-dwarf stars are promising targets in the exploration of potentially habitable planets. Their properties, falling between G and M dwarfs, provide an optimal trade-off between the prospect of habitability and […]
