In the past few years, significant advances have been made in understanding the
distributions of exoplanet populations and the architecture of planetary systems. We review …

Exoplanets can be detected with various observational techniques. Among them, radial
velocity (RV) has the key advantages of revealing the architecture of planetary systems and …

Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

Context. Several planetary formation models have been proposed to explain the observed
abundance and variety of compositions of super-Earths and mini-Neptunes. In this context …

Accumulation of new data on stellar hierarchical systems and the progress in numerical
simulations of their formation open the door to genetic classification of these systems, where …

We investigate the underlying distribution of orbital eccentricities for planets around early-to-
mid M dwarf host stars. We employ a sample of 163 planets around early-to mid-M dwarfs …

Multiplanet systems are valuable arenas for investigating exoplanet architectures and
comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf …

Compact nonresonant systems of sub-Jovian planets are the most common outcome of the
planet formation process. Despite exhibiting broad overall diversity, these planets also …

The planets within compact multiplanet systems tend to have similar sizes, masses, and
orbital period ratios, like" peas in a pod." This pattern was detected when considering …

The Rossiter-McLaughlin (RM) effect is a method that allows us to measure the orbital
obliquity of planets, which is an important constraint that has been used to understand the …
