Long-term evolution of accretion discs in Be/X-ray binaries [PDF]
, 2006 We numerically study the long-term evolution of the accretion disc around the neutron star in a coplanar Be/X-ray binary with a short period and a moderate eccentricity. From three dimensional Smoothed Particle Hydrodynamics simulations, we find that the

Mass Transfer in Mira-Type Binaries
Open Astronomy, 2012 Detached, symbiotic binaries are generally assumed to interact via Bondi-Hoyle-Littleton (BHL) wind accretion. However, the accretion rates and outflow geometries that result from this mass-transfer mechanism cannot adequately explain the observations of

Acclimatization Drives Differences in Reef-Building Coral Calcification Rates
Diversity, 2020 Coral reefs are susceptible to climate change, anthropogenic influence, and environmental stressors. However, corals in Kāneʻohe Bay, Hawaiʻi have repeatedly shown resilience and acclimatization to anthropogenically-induced rising temperatures and ...

A Long-Term Study of Ultraluminous X-ray Sources in NGC 891
Universe, 2021 We perform empirical fits to the Chandra and XMM-Newton spectra of three ultraluminous X-ray sources (ULXs) in the edge-on spiral galaxy NGC 891, monitoring the region over a 17-year time window.

Super-Eddington Accretion Disks around Supermassive Black Holes [PDF]
Astrophysical Journal, 2017 We use global three-dimensional radiation magnetohydrodynamical simulations to study accretion disks onto a black hole with accretion rates varying from to . We initialize the disks with a weakly magnetized torus centered at either 50 or 80 gravitational

Massive star formation by accretion [PDF]
Astronomy & Astrophysics, 2015 Massive stars likely form by accretion and the evolutionary track of an accreting forming star corresponds to what is called the birthline in the HR diagram. The shape of this birthline is quite sensitive to the evolution of the entropy in the accreting star.

The Accretion Disc Particle Method for Simulations of Black Hole Feeding and Feedback
, 2010 Black holes grow by accreting matter from their surroundings. However, angular momentum provides an efficient natural barrier to accretion and so only the lowest angular momentum material will be available to feed the black holes.

A New Parameter In Accretion Disk Model
, 2000 Taking optically thin accretion flows as an example, we investigate the dynamics and the emergent spectra of accretion flows with different outer boundary conditions (OBCs) and find that OBC plays an important role in accretion disk model.
