We performed global three-dimensional magnetohydrodynamic simulations of accretion on to a star with magnetic field and other properties close to those observed in the classical T Tauri star BP Tau. We observed in the simulations that the disc is disrupted by the dipole component and matter flows towards the star in two funnel streams which form two accretion spots below the dipole magnetic poles. The octupolar component becomes dynamically important very close to the star and it redirects the… Expand
Accretion dynamics in the classical T Tauri star V2129 Ophiuchi
We analyze the photometric and spectroscopic variability of the classical T Tauri star V2129 Oph over several rotational cycles to test the dynamical predictions of magnetospheric accretion models.Expand
Accretion onto stars with octupole magnetic fields: Matter flow, hot spots and phase shifts
Abstract Recent measurements of the surface magnetic fields of classical T Tauri stars (CTTSs) and magnetic cataclysmic variables show that their magnetic fields have a complex structure.Expand
Magnetospheric Accretions and the Inner Winds of Classical T Tauri Stars
Abstract Recent spectropolarimetric observations suggest that young low-mass stars such as classical T Tauri stars (CTTSs) possess relatively strong (~kG) magnetic field. This supports a scenario inExpand
Analytic and numerical models of the 3D multipolar magnetospheres of pre-main sequence stars
Traditionally models of accretion of gas on to T Tauri stars have assumed a dipole stellar magnetosphere, partly for simplicity, but also due to the lack of information about their true magneticExpand
Classical T Tauri stars : magnetic fields, coronae, and star-disc interactions
The magnetic fields of young stars set their coronal properties and control their spin evolution via the star–disc interaction and outflows. Using 14 magnetic maps of 10 classical T Tauri starsExpand
New view of the corona of classical T Tauri stars: Effects of flaring activity in circumstellar disks
Context. Classical T Tauri stars (CTTSs) are young low-mass stellar objects that accrete mass from their circumstellar disks. They are characterized by high levels of coronal activity, as revealed byExpand
MHD simulations of accretion onto a dipolar magnetosphere - II. Magnetospheric ejections and stellar spin-down
Aims. This paper examines the outflows associated with the interaction of a stellar magnetosphere with an accretion disk. In particular, we investigate the magnetospheric ejections (MEs) due to theExpand
Are the outflows in FU Orionis systems driven by the stellar magnetic field
FU Orionis (FUOR) outbursts are major optical brightening episodes in low-mass protostars that evidently correspond to rapid mass-accretion events in the innermost region of a protostellar disc. TheExpand
Spin Evolution of Accreting Young Stars. II. Effect of Accretion-Powered Stellar Winds
We present a model for the rotational evolution of a young, solar-mass star interacting magnetically with an accretion disk. As in a previous paper (Paper I), the model includes changes in the star'sExpand
Radiatively efficient magnetized Bondi accretion
We have carried out a numerical study of the effect of large-scale magnetic fields on the rate of accretion from a uniform, isothermal gas onto a resistive, stationary point mass. Only mass, notExpand


Global 3D simulations of disc accretion on to the classical T Tauri star V2129 Oph
The magnetic field of the classical T Tauri star V2129 Oph can be modelled approximately by superposing slightly tilted dipole and octupole moments, with polar magnetic field strengths of 0.35 andExpand
Coronal structure of the classical T Tauri star V2129 Oph
The nature of the magnetic coupling between T Tauri stars and their discs determines not only the mass accretion process but possibly the spin evolution of the central star. We have taken a recentlyExpand

The non-dipolar magnetic fields of accreting T Tauri stars
Models of magnetospheric accretion on to classical T Tauri stars often assume that stellar magnetic fields are simple dipoles. Recently published surface magnetograms of BP Tau and V2129 Oph haveExpand
