Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host
stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet …

A general theory of planet formation has been a topic of intense study over many years. The
interest in such a theory emerges naturally from asking the question of where our planet …

The merger rate of stellar-mass black hole binaries (sBHBs) inferred by the Advanced Laser
Interferometer Gravitational-Wave Observatory (LIGO) suggests the need for an efficient …

Giant planets embedded in protoplanetary disks (PPDs) can create annulus density gaps
around their orbits in the type-II regime, potentially responsible for the ubiquity of annular …

Context. The increasing number of newly detected exoplanets at short orbital periods raises
questions about their formation and migration histories. Planet formation and migration …

Abstract Atacama Large Millimeter/submillimeter Array (ALMA) continuum observations of
thermal emission from the dust component of protoplanetary disks have revealed an …

Context. Type-II migration of giant planets has a speed proportional to the disc's viscosity for
values of the α viscosity parameter larger than 10− 4. Previous studies based on two …

The migration of planetary cores embedded in a protoplanetary disk is an important
mechanism within planet-formation theory, relevant for the architecture of planetary systems …

In radiatively inefficient, laminar protoplanetary discs, embedded planets can excite a
buoyancy response as gas gets deflected vertically near the planet. This results in vertical …

Low-mass planets migrate in the type-I regime. In the inviscid limit, the contrast between the
vortensity trapped inside the planet's corotating region and the background disc vortensity …
