Accretion-powered stellar winds. III. spin-equilibrium solutions [PDF]

open access: yes, 2008
We compare the stellar wind torque calculated in a previous work (Paper II) to the spin-up and spin-down torques expected to arise from the magnetic interaction between a slowly rotating (∼10% of breakup) pre-main-sequence star and its accretion disk ...

The Radiative Transfer in Accretion Discs with Linear Plank Function: Role of Scattering Effect [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2020
Radiative transfer in a geometrically thin accretion disc with fnite optical depth is considered under the plane-parallel approximation. The Eddington factor that is defned as the ratio of the mean intensity to radiation stress tensor, is assumed be ...

Accreting white dwarf [PDF]

open access: yesProceedings of Supernovae: lights in the darkness — PoS(SUPERNOVA), 2008
Thermonuclear (type Ia) supernovae are explosions in accreting white dwarfs, but the exact scenario leading to these explosions is still unclear. An important step to clarify this point is to understand the behaviour of accreting white dwarfs in close binary systems.

Unveiling shoreline dynamics and remarkable accretion rates in Lake Eğirdir (Turkey) using DSAS. The implications of climate change on lakes

open access: yesTeMA: Journal of Land Use, Mobility and Environment, 2023
Lakes and their shorelines are important ecosystem areas with the diversity of living species they host. In addition, lakes are an almost indispensable resource for humans as a source of fresh water.

Accreted or Not Accreted? The Fraction of Accreted Mass in Galaxies from Simulations and Observations

open access: yes, 2021
In the two-phase scenario of galaxy formation, a galaxy's stellar mass growth is first dominated by in-situ star formation, and subsequently by accretion. We analyse the radial distribution of the accreted stellar mass in ~500 galaxies from the hydrodynamical cosmological simulation Magneticum.

Accretion and star formation in quasars [PDF]

open access: yes, 2015
Studying the interplay of accretion and star formation is crucial to our understanding of galaxy evolution. The new generation of radio surveys are able to play a key role in this area, since both processes produce radio emission.

The effect of droplet size and liquid water content on ice accretion and aerodynamic coefficients of tower legs [PDF]

open access: yes, 2013
An experimental study was conducted to examine the effects of varying the cloud characteristics on ice accretion on tower legs and on the aerodynamic coefficients around the ice-covered legs.

Reference Array and Design Consideration for the Next-Generation Event Horizon Telescope

open access: yesGalaxies, 2023
We describe the process to design, architect, and implement a transformative enhancement of the Event Horizon Telescope (EHT). This program—the next-generation Event Horizon Telescope (ngEHT)—will form a networked global array of radio dishes capable of ...
