Prospects for Detection of Exoplanet Magnetic Fields Through Bow-Shock Observations During Transits
planet-star interactions planets and satellites magnetic fields—stars
2010/11/16
An asymmetry between the ingress and egress times was observed in the near-UV light curve
of the transit planet WASP-12b. Such asymmetry led us to suggest that the early ingress in
the UV light curv...
We present here evidence for the observation of the magneto-hydrodynamic
(MHD) sausage modes in magnetic pores in the solar photosphere. Further evidence for the omnipresent nature of acoustic global...
Magnetic field structure in a high-mass outflow/disk system
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
To characterize the magnetic field structure of the outflow and core region within a prototypical high-mass star-forming region, we analyzed polarized CO(3-2) - for the first time observed with the Su...
Investigation of Dynamics of Self-Similarly Evolving Magnetic Clouds
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Magnetic clouds (MCs) are "magnetized plasma clouds" moving in the solar wind. MCs transport magnetic flux and helicity away from the Sun. These structures are not stationary but feature temporal evol...
Faraday rotation: effect of magnetic field reversals
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
The standard formula for the rotation measure, RM, which determines the position angle, $\psi={\rm RM}\lambda^2$, due to Faraday rotation, includes contributions only from the portions of the ray path...
Turbulence and magnetic spots at the surface of hot massive stars
Solar and Stellar Astrophysics (astro-ph.SR) Fluid Dynamics (physics.flu-dyn)
2010/12/29
Hot luminous stars show a variety of phenomena in their photospheres and in their winds which still lack clear physical explanations at this time. Among these phenomena are non-thermal line broadening...
Observations of magnetic fields in hot stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
The presence of magnetic fields at the surfaces of many massive stars has been suspected for decades, to explain the observed properties and activity of OB stars.
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...
