Episodic 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...
متن کاملMagnetically-driven jets from Keplerian accretion discs
Non-relativistic, magnetically-driven jets are constructed by taking self-consistently into account the feedback on the underlying accretion disc. It is shown that such jets are mostly described by the ejection index ξ = d ln Ṁa/d ln r, which is a local measure of the disc ejection efficiency. This parameter is found to lie in a very narrow range, due to constraints imposed by both the disc ver...
متن کاملMagnetorotational instability in protoplanetary discs
We investigate the linear growth and vertical structure of the magnetorotational instability (MRI) in weakly ionised, stratified accretion discs. The magnetic field is initially vertical and dust grains are assumed to have settled towards the midplane, so charges are carried by electrons and ions only. Solutions are obtained at representative radial locations from the central protostar for diff...
متن کاملOvercoming the Accretion Barrier in Protoplanetary Discs by Conditions Prevailing at Chondrule Formation
To form planets in protoplanetary discs, micrometer sized dust particles need to grow by hit-and-stick collisions to km sized planetesimals, followed by further proto-planetary growth by gravitational forces. A serious obstacle of coagulation of large bodies is their increasing collision velocity: while larger bodies orbit with Keplerian velocity, small dust couples to the gas that rotates with...
متن کاملHave 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...
