Nebular gas drag and planetary accretion with eccentric high-mass planets
(2013-04-08)
Aims.We investigate the dynamics of pebbles immersed in a gas disk interacting with a planet on an eccentric orbit. The model has a prescribed gap in the disk around the location of the planetary orbit, as is expected for ...
Investigating the magnetospheric accretion process in the young pre-transitional disk system DoAr 44 (V2062 Oph)
(European Southern Observatory, 2020)
Context. Young stars interact with their accretion disk through their strong magnetosphere.
Aims. We aim to investigate the magnetospheric accretion/ejection process in the young stellar system DoAr 44 (V2062 Oph).
Methods. ...
A METHOD FOR THE STUDY OF ACCRETION DISK EMISSION IN CATACLYSMIC VARIABLES. I. THE MODEL
(IOP PUBLISHING LTD, 2011)
We have developed a spectrum synthesis method for modeling the ultraviolet (UV) emission from the accretion disk from cataclysmic variables (CVs). The disk is separated into concentric rings, with an internal structure ...
THE ROLE OF TURBULENT MAGNETIC RECONNECTION IN THE FORMATION OF ROTATIONALLY SUPPORTED PROTOSTELLAR DISKS
(IOP PUBLISHING LTDBRISTOL, 2012)
The formation of protostellar disks out of molecular cloud cores is still not fully understood. Under ideal MHD conditions, the removal of angular momentum from the disk progenitor by the typically embedded magnetic field ...
Nonthermal processes in hot accretion flows onto supermassive black holes: an inhomogeneous model
(EDP Sciences, 2021-05)
Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a cold optically thick disk, plus a hot, low ...

(EDP, 2020)
Context. Young stars interact with their accretion disk through their strong magnetosphere.Aims. We aim to investigate the magnetospheric accretion/ejection process in the young stellar system DoAr 44 (V2062 Oph).Methods. ...
