Rapid and predictive planet population synthesis model (RAPPS)
Astronomy & AstrophysicsContext. Exoplanet surveys have revealed a large diversity of planetary systems. Explaining the origin of such diversity requires integrated models of planet formation.

Apparent Stellar Wobble by a Planet in a Circumstellar Disk:
, 2007 Astrometric detection of a stellar wobble on the plane of the sky will provide us a next breakthrough in searching extrasolar planets. The Space Interferometry Mission (SIM) is expected to achieve a high-precision astrometry as accurate as 1 as, which

Astronomy & AstrophysicsLate infall can replenish the building materials of planets in protoplanetary disks and dramatically alter their structural evolution. The resulting pressure bumps effectively accumulate dust, facilitate grain coagulation, and trigger planetesimal ...

Nested Grid Calculations of Disk-Planet Interaction
, 2002 We study the evolution of embedded protoplanets in a protostellar disk using very high resolution nested-grid computations. This method allows us to perform global simulations of planets orbiting in disks and, at the same time, to resolve in detail the

The Astrophysical JournalAbstract β Pictoris's well-studied debris disk and two known giant planets, in combination with the stability of the Hubble Space Telescope’s Space Telescope Imaging Spectrograph (HST/STIS) (and now also JWST), offers a unique opportunity to test planet–disk interaction models and to observe recent planetesimal ...

Disk dynamics and planet migration
, 2010 We review models of protoplanetary disks. In the earlier stages of evolution, disks are subject to gravitational instabilities that redistribute mass and angular momentum on short timescales. Later on, when the mass of the disk is below ten percent or so

A Bridge between Young Stars Formed by Gravitational Interaction
The Astrophysical Journal LettersThe majority of stars are born in clustered environments. In these environments, close encounters between young stars with planet-forming disks are expected to occur frequently. However, direct evidence of such interactions remains rare.

Breaking Giant Chains: Early-stage Instabilities in Long-period Giant Planet Systems
The Astrophysical JournalOrbital evolution is a critical process that sculpts planetary systems, particularly during their early stages where planet–disk interactions are expected to lead to the formation of resonant chains.

The Astrophysical JournalWhile stellar jets and outflows are fueled by accretion from disks, their direct influence on disks remain unexplored. Here, we revisit Atacama Large Millimeter/submillimeter Array observations of ^12 CO ( J = 2–1) line emission for the young stellar ...

12CO Ro-Vibrational Spectroscopy of Protoplanetary Disks: Inferring Planet-Disk Interactions [PDF]
Observing and studying planets around young stars during their initial formation stages is essential for understanding the physics of their formation. Protoplanetary disks are the host sites of planets, and they exhibit substructures that hint towards ...
