Convergent disk migration has long been suspected to be responsible for forming planetary
systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time …

One of the most important developments in exoplanet science in the past decade is the
discovery of multi-planet systems with sub-Neptune-sized planets interior to 1~ AU. This …

NASA's Kepler mission revealed that~ 30% of Solar-type stars harbour planets with sizes
between that of Earth and Neptune on nearly circular and coplanar orbits with periods less …

ABSTRACT TRAPPIST-1 is an 0.09 M⊙ star, which harbours a system of seven Earth-sized
planets. Two main features stand out:(i) all planets have similar radii, masses, and …

Context. HR 8799 is a young planetary system composed of four planets and a double
debris belt. Being the first multi-planetary system discovered with the direct imaging …

A gap in exoplanets' radius distribution has been widely attributed to the photoevaporation
threshold of their progenitors' gaseous envelope. Giant impacts can also lead to substantial …

A system of four super-Jupiter planets around HR 8799 is the first multiplanet configuration
discovered via the direct imaging technique. Despite over a decade of research, the …

The theory of Type I migration has been widely used in many studies. Transiting multiplanet
systems offer us the opportunity to examine the consistency between observation and …

Over the past several decades, thousands of planets have been discovered outside our
Solar System. These planets exhibit enormous diversity, and their large numbers provide a …
