York University astrophysicists detect ultra-fast winds near supermassive black hole
York University astrophysicists ultra-fast winds supermassive black hole
2016/3/28
New research led by astrophysicists at York University has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole.“We’re talking wind speeds of 20 per cent the ...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
High spatial resolution monitoring of the activity of BA supergiant winds
High spatial resolution the activity BA supergiant winds
2011/1/13
There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently commissioned, opera...
The rapid rotation (P=0.44 d) of the M dwarf V374Peg (M4) along with its intense magnetic field point toward magneto-centrifugal acceleration of a coronal wind. In this work, we investigate the struct...
The Physics of Disk Winds, Jets,and X-ray Variability in GRS 1915+105
Disk Winds Jets X-ray Variability
2011/1/11
We present new insights about accretion and ejection physics based on joint RXTE/Chandra HETGS studies of rapid X-ray variability in GRS 1915+105. For the first time, with fast phase-resolved spectros...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds
emission lines globular clusters
2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
Spiralling out of control: 3D hydrodynamical modelling of the colliding winds in $\eta\thinspace$Carinae
hydrodynamics stars:early-type X-rays stars - stars binaries - stars:winds
2010/11/10
Three dimensional (3D) adaptive-mesh refinement (AMR) hydrodynamical simulations of the windwind collision between the enigmatic super-massive star η Car and its mysterious companion star are presente...
On the source of dense outflows from T Tauri Stars. and III. Winds driven from the star-disc shear layer
stars pre-main-sequence stars: winds outflows stars circumstellar matter – stars formation
2010/11/11
Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (Te ≃ 80, 000 K) and dense (ne ≃ 1010 cm−3) component associated with the large scale jet. ...
The interactions of winds from massive young stellar objects
interactions of winds massive young stellar objects
2010/11/10
The supersonic stellar and disk winds possessed by massive young stellar objects will produce
shocks when they collide against the interior of a pre-existing bipolar cavity (resulting from an earlier...
On the interaction of jets with stellar winds in XRBs
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
We present the first three-dimensional simulations of the evolution of a microquasar jet inside the binary-star system. The aim is to study the interaction of these jets with the stellar wind from a m...
Transport of First Rocks of The Solar System by X-winds
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
It has been suggested that chondrules and calcium-aluminum-rich inclusions (CAIs) were formed at the inner edge of the protoplanetary disk and then entrained in magnetocentrifugal X-winds. We study tr...
Exploring the connection of weak winds and magnetic fields
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
The theory of radiatively driven winds successfully explains the key points of the stellar winds of hot massive stars. However, there is an apparent break-down of this paradigm at L/Lsun<5.2: the stel...
Magnetic fields, winds and X-rays of the massive stars in the Orion Nebula Cluster
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
In some massive stars, magnetic fields are thought to confine the outflowing radiatively-driven wind. Although theoretical models and MHD simulations are able to illustrate the dynamics of such a magn...
