Have protoplanetary discs formed planets
It has recently been noted that many discs around T Tauri stars appear to comprise only a few Jupiter masses of gas and dust. Using millimetre surveys of discs within six local star formation regions, we confirm this result, and find that only a few per cent of young stars have enough circumstellar material to build gas giant planets, in standard core accretion models. Since the frequency of ob...
متن کاملCritical Protoplanetary Core Masses in Protoplanetary Disks and the Formation of Short–period Giant Planets
We study a solid protoplanetary core undergoing radial migration in a protoplanetary disk. We consider cores in the mass range ∼ 1 − 10 M⊕ embedded in a gaseous protoplanetary disk at different radial locations. We suppose the core luminosity is generated as a result of planetesimal accretion and calculate the structure of the gaseous envelope assuming hydrostatic and thermal equilibrium. This ...
متن کاملEpisodic accretion in magnetically layered protoplanetary discs
We study protoplanetary disc evolution assuming that angular momentum transport is driven by gravitational instability at large radii, and magnetohydrodynamic (MHD) turbulence in the hot inner regions. At radii of the order of 1 AU such discs develop a magnetically layered structure, with accretion occurring in an ionized surface layer overlying quiescent gas that is too cool to sustain MHD tur...

15 صفحه اولDust evolution in protoplanetary accretion disks
The time evolution of dust particles in circumstellar disk-like structures around protostars and young stellar objects was investigated. For the first time, we coupled the dust evolution directly to the evolution of the disk and followed the influence of opacity changes due to collisional aggregation on the dynamics of the disk. For that purpose, we numerically simulated the dynamical evolution...
