Homologous Flares and Magnetic Field Topology in Active Region NOAA 10501 on 20 November 2003
Active Regions Magnetic Fields Flares Dynamics Flares Relation
2010/11/11
We present and interpret observations of two morphologically homologous flares that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homologous H ribbons and ...
The magnetic field in the NGC 2024 FIR 5 dense core
individual ISM magnetic fields Polarization Stars formation Techniques interferometric
2010/11/10
We used the Submillimeter Array (SMA) to observe the thermal polarized dust emission from the protostellar source NGC 2024 FIR 5. The polarized emission outlines a partial hourglass morphology for the...
Effects of non-uniform interstellar magnetic field on synchrotron X-ray and inverse-Compton gamma-ray morphology of SNRs
Magnetohydrodynamics (MHD) Radiation mechanisms non-thermal Shock waves ISM
2010/11/12
Context. Observations of SNRs in X-ray and γ-ray bands promise to contribute with important information in our understanding of the kinematics of charged particles and magnetic fields in the vicinity ...
A low-magnetic-field Soft Gamma Repeater
High Energy Astrophysical Phenomena (astro-ph.HE) Galaxy Astrophysics (astro-ph.GA)
2011/1/4
Soft gamma repeaters and anomalous x-ray pulsars form a rapidly increasing group of x-ray sources exhibiting sporadic emission of short bursts. They are believed to be magnetars, i.e. neutron stars po...
Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the mag...
Magnetic field effects on some astrophysical properties of Quark Stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
This thesis aims to study how amending certain astrophysical observable of quark stars due to presence of magnetic field. To do this we need to obtain Equation of State (EOS) and consider the stabilit...
