Faraday Rotation Measure due to the Intergalactic Magnetic Field II: the Cosmological Contribution
intergalactic medium — large-scale structure of universe —magnetic fields — polarization
font style='font-size:12px;'>
2011/8/24
We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on turbulence dynamo in th...
Induced Rotation in 3D Simulations of Core Collapse Supernovae: Implications for Pulsar Spins
Induced Rotation 3D Simulations Core Collapse Supernovae

2011/1/11
It has been suggested that the observed rotation periods of radio pulsars might be induced by a non-axisymmetric spiral-mode instability in the turbulent region behind the stalled supernova bounce sho...

We continue our studies on stellar latitudinal differential rotation. The presented work is a sequel of the work of Reiners et al. who studied the spectral line broadening profile of hundreds of stars...
The Mass-Radius(-Rotation?) Relation for Low-Mass Stars

The fundamental properties of low-mass stars are not as well understood as those of their more
massive counterparts. The best method for constraining these properties, especially masses and radii,is ...

Anomalous X-ray pulsars and soft gamma repeaters have recently emerged as a unified class of neutron stars, identified by dramatic X-ray and gamma-ray outbursts and via luminous X-ray pulsations, both...
Differential Rotation and Magnetism in Simulations of Fully Convective Stars
Solar and Stellar Astrophysics (astro-ph.SR) Fluid Dynamics (physics.flu-dyn)
font style='font-size:12px;'>

Stars of sufficiently low mass are convective throughout their interiors, and so do not possess an internal boundary layer akin to the solar tachocline.
Rotation Speed of the First Stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/24
We estimate the rotation speed of Population III (Pop III) stars within a minihalo at z ~ 20 using a smoothed particle hydrodynamics (SPH) simulation, beginning from cosmological initial conditions. W...
Rotation of the Milky Way and the formation of the Magellanic Stream
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/24
We studied the impact of the revisited values for the LSR circular velocity of the Milky Way (Reid et al. 2004) on the formation of the Magellanic Stream. The LSR circular velocity was varied within i...

We analyze a new kinematic survey that includes accurate proper motions derived from SDSS DR7 positions, combined with multi-epoch measurements from the GSC-II database. By means of the SDSS spectro-p...
