We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

Over the past two decades, large strides have been made in the field of planet formation. Yet
fundamental questions remain. Here we review our state of understanding of five …

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 …

The radius distribution of small, close-in exoplanets has recently been shown to be bimodal.
The photoevaporation model predicted this bimodality. In the photoevaporation scenario …

Some recently discovered short-period Earth-to Neptune-sized exoplanets (super-Earths)
have low observed mean densities that can only be explained by voluminous gaseous …

We investigate the minimum planet mass that produces observable signatures in infrared
scattered light and submillimetre (submm) continuum images and demonstrate how these …

As spiral waves driven by a planet in a gaseous disk steepen into a shock, they deposit
angular momentum, opening a gap in the disk. This has been well studied using both linear …

Stellar-mass binary black holes (BBHs) embedded in active galactic nucleus (AGN) discs
are possible progenitors of black hole mergers detected in gravitational waves by …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

The atmospheres of small, close-in exoplanets are vulnerable to rapid mass loss during
protoplanetary disc dispersal via a process referred to as 'boil-off', in which confining …
