Formation of Accretion Disks in Close-Binary Systems with Magnetic Fields
Accretion Disks Close-Binary Systems Magnetic Fields
2011/1/10
We have developed a three-dimensional numerical model and applied it to simulate plasma flows in semi-detached binary systems whose accretor possesses a strong intrinsic magnetic field. The model is b...
Ultrahigh-energy nuclei, photons, and magnetic fields
Ultrahigh-energy nuclei photons magnetic fields
2011/1/10
Combined recent data from cosmic-ray detectors and gamma-ray detectors have produced some surprising insights regarding the sources of ultrahigh-energy cosmic rays (UHECRs), magnetic fields inside and...
Trapped, Two-Armed, Nearly Vertical Oscillations in Disks with Toroidal Magnetic Fields
Trapped Two-Armed Nearly Vertical Oscillations
2011/1/13
We have examined trapping of two-armed ($m=2$) nearly vertical oscillations (vertical p-mode) in vertically isothermal ($c_{\rm s}=$ const.) relativistic disks with toroidal magnetic fields. The magne...
Thermal evolution and lifetime of intrinsic magnetic fields of Super Earths in habitable zones
Thermal evolution intrinsic magnetic fields
2011/1/11
We have numerically studied the thermal evolution of various-mass terrestrial planets in habitable zones, focusing on duration of dynamo activity to generate their intrinsic magnetic fields, which may...
The Interplay of Magnetic Fields, Fragmentation and Ionization Feedback in High-Mass Star Formation
Magnetic Fields Fragmentation High-Mass Star Formation
2011/1/13
Massive stars disproportionately influence their surroundings. How they form has only started to become clear recently through radiation gas dynamical simulations. However, until now, no simulation ha...
Dark energy, non-minimal couplings and the origin of cosmic magnetic fields
Dark energy non-minimal couplings the origin of cosmic magnetic fields
2011/1/10
In this work we consider the most general electromagnetic theory in curved space-time leading to linear second order differential equations, including non-minimal couplings to the space-time curvature...
Primordial magnetic fields with X-ray and S-Z cluster survey
Primordial magnetic fields X-ray and S-Z cluster survey
2011/1/10
The effect of primordial magnetic fields on X-ray or S-Z galaxy cluster survey is investigated. After recombination, the primordial magnetic fields generate additional density fluctuations. Such densi...
The Hanle Effect as a Diagnostic of Magnetic Fields in Stellar Envelopes. V. Thin Lines from Keplerian Disks
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
This paper focuses on the polarized profiles of resonance scattering lines that form in magnetized disks. Optically thin lines from Keplerian planar disks are considered. Model line profiles are calcu...
