Non-stationary dynamo & magnetospheric accretion processes of the classical T Tauri star V2129 Oph
JF Donati, J Bouvier, FM Walter +11
We report here the first results of a multi-wavelength campaign focussing on magnetospheric accretion processes of the classical TTauri star (cTTS) V2129Oph. In this paper, we pres…
The Moving Hotspots model for kHz QPOs in accreting neutron stars
Matteo Bachetti, Marina Romanova
3D MHD simulation of accretion onto neutron stars have shown in the last few years that the footprint (hotspot) of the accretion flow changes with time. Two different kinds of accr…
Global 3D Simulations of Disc Accretion onto the classical T Tauri Star BP Tauri
M. Long, M. M. Romanova, A. K. Kulkarni +1
The magnetic field of the classical T Tauri star BP Tau can be approximated as a superposition of dipole and octupole moments with respective strengths of the polar magnetic fields…
One-sided Outflows/Jets from Rotating Stars with Complex Magnetic Fields
R. V. E. Lovelace, M. M. Romanova, G. V. Ustyugova +1
We investigate the generation of intrinsically asymmetric or {\it one-sided} outflows or jets from disk accretion onto rotating stars with complex magnetic fields using axisymmetri…
