Evidence for a correlation between mass accretion rates onto young stars and the mass of their protoplanetary disks [PDF]
, 2016 A relation between the mass accretion rate onto the central young star and the mass of the surrounding protoplanetary disk has long been theoretically predicted and observationally sought.

Regulation of black-hole accretion by a disk wind during a violent outburst of V404 Cygni [PDF]
Nature, 2016 A sustained, neutral wind from the outer accretion disk is observed in the transient black hole V404 Cygni during a violent outburst; this unusual wind, which expands at one per cent of the speed of light and triggers a nebular phase once accretion drops

Accretion disc particle accretion in major merger simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 A recent approach to simulating localized feedback from active galactic nuclei by Power et al. (2011) uses an accretion disc particle to represent both the black hole and its accretion disc. We have extrapolated and adapted this approach to simulations of Milky Way-sized galaxy mergers containing black holes and explored the impact of the various ...

Electrical characteristics of an energised conductor under various weather conditions
High Voltage, 2017 When a transmission line is subjected to adverse weather conditions, rain drops or ice can be formed on its surface, leading to discharge phenomena known as corona.

On the orbital evolution of supermassive black hole binaries with circumbinary accretion discs [PDF]
, 2017 Gaseous circumbinary accretion discs provide a promising mechanism to facilitate the mergers of supermassive black holes (SMBHs) in galactic nuclei. We measure the torques exerted on accreting SMBH binaries, using 2D, isothermal, moving-mesh, viscous ...

Hydrodynamics of Accretion Columns [PDF]
Astrophysics and Space Science, 1987 AbstractA detailed understanding of how the infalling matter in accretion columns is decelerated is essential for the calculation of the emitted radiation. On neutron stars, the deceleration takes place mainly by the interaction of the plasma with radiation, at least for the high-luminosity sources.

UniverseAccretion and migration usually proceed concurrently for giant planet formation in the natal protoplanetary disks. Recent works indicate that the concurrent accretion onto a giant planet imposes significant impact on the planetary migration dynamics in ...

Highly Magnetized Accreting Pulsars: Are There Accreting Magnetars?
Acta Polytechnica CTU Proceedings, 2014 2S 0114+650, GX 301-2, IGR J16358-4726, X Per, 4U 2206+54, SXP 1062, and 3A 1954+319 are thought to possess high magnetic elds. They have recently been named accreting magnetars, or highly magnetized accreting pulsars. In this work their properties are reviewed.

Universe, 2019 There is increasing observational evidence that short and long Gamma-ray bursts (GRBs) originate in different subclasses, each one with specific energy release, spectra, duration, etc, and all of them with binary progenitors.
