Numerical estimates of the accretion rate on to intermediate-mass black holes
(Wiley Blackwell Publishing, Inc, 2013-04)
The existence of intermediate-mass (∼103 M⊙) black holes (IMBHs) in the centre of glob- ular clusters has been suggested by different observations. The X-ray sources observed in NGC 6388 and in G1 in M31 could be interpreted ...
Accretion from debris disks onto white dwarfs. Fingering (thermohaline) instability and derived accretion rates
(Edp Sciences, 2013-09)
Context. Recent observations of a large number of DA and DB white dwarfs show evidence of debris disks, which are the remnants of old planetary systems. The infrared excess detected with Spitzer and the lines of heavy ...
X-Ray Determination of the Variable Rate of Mass Accretion onto TW Hydrae
(IOP Publishing, 2012-11-05)
Diagnostics of electron temperature (Te), electron density (ne), and hydrogen column density (NH) from the Chandra High Energy Transmission Grating spectrum of He-like Ne ix in TW Hydrae (TW Hya), in conjunction with a ...
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 ...
Structural overprint of a late Paleozoic accretionary system in north-central Chile (34°-35°S) during post-accretional deformation
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2009)
Misaligned snowplough effect and the electromagnetic counterpart to black hole binary mergers
(2019-01-01)
We estimate the accretion rates produced when a circumprimary gas disc is pushed into the primary supermassive black hole (SMBH) by the tidal force of the decaying secondary during a SMBH merger. Using the 3D Smoothed ...
