Origin Of Coronal High Temperature
center temperature gasification substances bian sphere coronal high
2015/6/2
In sun center, pressure least direction is ends of sun spin axis. Thus, sun center ultra-high temperature gasification substance jet out along sun's rotation axis, through photosphere, chromosphere, t...
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
2011/10/20
We report a spectroscopic analysis of an EIT wave event that occurred in active region 11081 on 2010 June 12 and was associated with an M2.0 class flare. The wave propagated near circularly. The south...
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 ...
Analysis of characteristic parameters of large-scale coronal waves observed by STEREO/EUVI
Analysis characteristic parameters large-scale coronal observed
2011/9/28
The kinematical evolution of four EUV waves, well observed by the Extreme UltraViolet Imager (EUVI) onboard the Solar-Terrestrial Relations Observatory (STEREO), is studied by visually tracking the wa...
Nonlinear force-free and potential field models of active-region and global coronal fields during the Whole Heliospheric Interval
Nonlinear force-free potential field models
2011/1/13
Between 2008/3/24 and 2008/4/2, the three active regions NOAA active regions 10987, 10988 and 10989 were observed daily by the Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector Spec...
Coronal Loops: Observations and Modeling of Confined Plasma
Coronal Loops Observations Confined Plasma
2011/1/13
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma. ...
The Genesis of an Impulsive Coronal Mass Ejection observed at Ultra-High Cadence by AIA on SDO
Impulsive Coronal Ultra-High Cadence AIA on SDO
2011/1/11
The study of fast, eruptive events in the low solar corona is one of the science objectives of the Atmospheric Imaging Assembly (AIA) imagers on the recently launched Solar Dynamics Observatory (SDO),...
Coronal Temperature Diagnostic Capability of the Hinode/X-Ray Telescope Based on Self-Consistent Calibration
Corona Instrumentation and Data Management
2010/11/15
The X-Ray Telescope (XRT) onboard the Hinode satellite is an X-ray imager that observes the solar corona with unprecedentedly high angular resolution (consistent with its 1′′ pixel size). XRT has nine...
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...
Uncovering Mechanisms of Coronal Magnetism via Advanced 3D Modeling of Flares and Active Regions
Uncovering Mechanisms of Coronal Magnetism 3D Modeling of Flares Active Regions
2010/11/15
The coming decade will see the routine use of solar data of unprecedented spatial and spectral resolution, time cadence, and completeness. To capitalize on the new (or soon to be available) facilities...
Damping of longitudinal magneto-acoustic oscillations in slowly varying coronal plasma
magnetohydrodynamics(MHD) - plasmas - Sun corona - waves
2010/11/15
We investigate the propagation of MHD waves in a homogenous, magnetized plasma in a weakly
stratified atmosphere, representing hot coronal loops. In most of earlier studies a time-independent equilib...
The effect of coronal radiation on a residual inner disk in the low/hard spectral state of black hole X-ray binary systems
accretion accretion disks — black hole physics —X-rays bi-naries — X-rays stars
2010/11/15
Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates, evaporation dominat...

2010/11/9
In recent work, Antiochos and coworkers argued that the boundary between the open and closed field regions on the Sun can be extremely complex with narrow corridors of open flux connecting seemingly d...
