Full-sun temperature distribution and classification of coronal structures
نویسندگان
چکیده
Coronal observations in X-rays show the sun has many dynamic features that can neither be imagined nor seen with the naked eye. The solar corona has a wide temperature range from less than 1MK (1,000,000K) to more than 10MK. The X-ray telescope (XRT) on board the Hinode satellite has 9 X-ray analysis filters to observe the almost of whole coronal plasma. Using the data observed with this telescope, we successfully derived the coronal temperature around the whole sun. We also found that coronal structures are nicely classified using the temperature and emission measure. Furthermore, the coronal structures were found to depend on the length of structure and the heating flux. This

Two-temperature Coronal Models from Soho/eit Observations
We present a method for deriving a twoÈthermal-component approximation to the di†erential emission measure distribution of plasma in the SunÏs corona in the temperature range to which the ExtremeUltraviolet Imaging Telescope (EIT) on the Solar and Heliospheric Observatory (SOHO) spacecraft is sensitive. EIT takes high-resolution full-disk coronal images in three of its four optimized channels b...

Coronal dimmings in both micro and macro scales, can be observed by extreme ultraviolet images, recorded from Solar Dynamics Observatory or Atmospheric Imaging Assembly (SDO/AIA). Mini-dimmings are sometimes associated with wave-like brightening, called coronal mass ejections. Here, the sun full disk images with 171 Å wavelenght, cadence of 2.5, and 0.6 arcsec cell size, were taken on 3 March ...
متن کاملFrom Solar and Stellar Flares to Coronal Heating: Theory and Observations of How Magnetic Reconnection Regulates Coronal Conditions
There is currently no explanation of why the corona has the temperature and density it has. We present a model which explains how the dynamics of magnetic reconnection regulates the conditions in the corona. A bifurcation in magnetic reconnection at a critical state enforces an upper bound on the coronal temperature for a given density. We present observational evidence from 107 flares in 37 su...
متن کاملJ an 2 00 9 Active region transition region loop populations and their relationship to the corona
The relationships among coronal loop structures at different temperatures is not settled. Previous studies have suggested that coronal loops in the core of an active region are not seen cooling through lower temperatures and therefore are steadily heated. If loops were cooling, the transition region would be an ideal temperature regime to look for a signature of their evolution. The Extremeultr...
متن کاملLarge-scale Solar Coronal Structures in Soft X-rays and Their Relationship to the Magnetic Flux
We have investigated the relationship between magnetic activity and coronal structures using soft X-ray data from the Yohkoh soft X-ray telescope and magnetic field data from the Kitt Peak Solar Observatory for the period of 1991–2001 and EUV data from the Solar and Heliospheric Observatory EUV Imaging Telescope for 1996–2001. The data are reduced to Carrington synoptic maps, which reveal two t...
