Mergers and ejections of black holes in globular clusters
black hole physics globular clusters numerical Mergers ejections
2012/2/23
We report on results of fully consistent N-body simulations of globular cluster models with N = 100 000 members containing neutron stars and black holes. Using the improved `algorithmic regularization...
Determination of Acceleration from 3D Reconstruction of Coronal Mass Ejections Observed by STEREO
Determination Acceleration Reconstruction Ejections Observed
2011/9/30
We employ a three-dimensional (3D) reconstruction technique, for the first time to study the kinematics of six coronal mass ejections (CMEs), using images obtained from the COR1 and COR2 coronagraphs ...
Solar Flares and Coronal Mass Ejections: A Statistically Determined Flare Flux-CME Mass Correlation
Flares Coronal mass ejections
2010/11/9
In an effort to examine the relationship between flare flux and corresponding CME mass, we temporally and spatially correlate all X-ray flares and CMEs in the LASCO and GOES archives from 1996 to 2006...
Astrophysical Jets : what can we learn from Solar Ejections?
Sun coronal mass ejections Galaxies jets Magnetic reconnection
2010/11/11
Ejections from the Sun can be observed with a higher resolution than in any other astrophysical object: can we build up on solar results and apply them to astrophysical objects? Aim of this work is to...
Accuracy and Limitations of Fitting and Stereoscopic Methods to Determine the Direction of Coronal Mass Ejections from Heliospheric Imagers Observations
Solar and Stellar Astrophysics (astro-ph.SR) Space Physics (physics.space-ph)
2010/12/28
Using data from the Heliospheric Imagers (HIs) onboard STEREO, it is possible to derive the direction of propagation of coronal mass ejections (CMEs) in addition to their speed with a variety of metho...
The Inversion of the Real Kinematic Properties of Coronal Mass Ejections by Forward Modeling
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The kinematic properties of coronal mass ejections (CMEs) suffer from the projection effects, and it is expected that the real velocity should be larger and the real angular width should be smaller th...
Dynamo generated field emergence through recurrent plasmoid ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Magnetic buoyancy is believed to drive the transport of magnetic flux tubes from the convection zone to the surface of the Sun. The magnetic fields form twisted loop-like structures in the solar atmos...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
I summarize the statistical, physical, and morphological properties of coronal mass ejections (CMEs) of solar cycle 23, as observed by the Solar and Heliospheric Observatory (SOHO) mission. The SOHO d...
EUV and Coronagraphic Observations of Coronal Mass Ejections
Sun corona coronal mass ejections post-eruptive arcades filaments prominence
2010/9/16
The Large Angle Spectrometric Coronagraph (LASCO)and Extreme-ultraviolet Imaging Telescope (EIT) onboard Solar and Heliospheric Observatory (SOHO) provide us with unprecedented multiwavelength observa...
Magnetic Source Regions of Coronal Mass Ejections
Coronal mass ejection flare filament eruption
2010/9/16
The majority of flare activity arises in active regions which contain sunspots, while Coronal Mass Ejection (CME) activity can also originate from decaying active regions and even so-called quiet sola...
Initiation and Propagation of Coronal Mass Ejections
Coronal mass ejections magnetic field
2010/9/16
This paper reviews recent progress in the research on the initiation and propagation of CMEs. In the initiation part, several trigger mechanisms are discussed; in the propagation part, the observation...
