Magnetospheric accretion on the fully-convective classical T Tauri star DN Tau [PDF]

open access: yes, 2013
The MaPP project is supported by the funding agencies of CFHT and TBL (through the allocation of telescope time) and by INSU/CNRS in particular, as well as by the French ‘Agence Nationale pour la Recherche’ (ANR).

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.

The X-ray position and optical counterpart of the accretion-powered millisecond pulsar XTE J1814−338 [PDF]

open access: yes, 2005
We report the precise optical and X-ray localization of the 3.2 ms accretion-powered X-ray pulsar XTE J1814-338 with data from the Chandra X-Ray Observatory as well as optical observations conducted during the 2003 June discovery outburst.

Full-scale runback ice: accretion and aerodynamic study [PDF]

open access: yes, 2010
The runback ice phenomenon is well-known for anti-icing or de-icing systems when the system is not evaporating 100% of the water impinging the surface.

TERRAIN TECTONICS OF THE CENTRAL ASIAN FOLDED BELT

open access: yesГеодинамика и тектонофизика, 2015
The terrain analysis concept envisages primarily a possibility of approximation of fragments / terrains of various geodynamic settings which belong to different plates. The terrain analysis can supplement the theory of plate tectonics in solving problems

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 ...

An automatic multi-stepping approach to aircraft ice prediction [PDF]

open access: yes, 2007
Flying an aircraft in icing conditions may seriously degrade its aerodynamical performance and threaten the flight safety. Over the years, new technologies and improved procedures have limited the potential risks caused by aircraft icing. Experimental

Self-Similar Solution of Hot Accretion Flow with Anisotropic Pressure

open access: yesUniverse, 2019
For the accretion flow in extremely low-luminosity active galactic nuclei, such as our Galactic center (Sgr A*) and M 87, the collisional mean-free path of ions may be much larger than its gyroradius.

Hot Accretion Flow in Two-Dimensional Spherical Coordinates: Considering Pressure Anisotropy and Magnetic Field

open access: yesUniverse, 2019
For systems with extremely low accretion rate, such as Galactic Center Sgr A* and M87 galaxy, the ion collisional mean free path can be considerably larger than its Larmor radius. In this case, the gas pressure is anisotropic to magnetic field lines.
