Physics of Coronal Loops
نویسنده
چکیده
Coronal loops are the basic elements of the solar corona and are responsible for the totality of the coronal X-ray emission. Loop physics is therefore important to understand the structure, heating, dynamics and evolution of the corona. A well-established and useful approach to study loop physics has been the detailed hydrodynamic modeling of the connned plasma, coupled to the synthesis of observable quantities to be compared to X-ray and EUV data, such as those from Yohkoh, NIXT and SOHO. In the light of this approach, some recent aspects, concerning microoares, cool loops, redshifts in UV lines, loop lamentation, and the are decay phase, are discussed.

Transversal oscillation of coronal loops that are interpreted as signatures of magneto hydrodynamics (MHD) waves are observed frequently in active region corona loops. The amplitude of this oscillation has been found to be strongly attenuated. The damping of transverse oscillation may be produced by the dissipation mechanism and the wake of the traveling disturbance. The damping of transversal ...
متن کاملRetrieval of Images with Coronal Loops from Solar Image Databases
We present a system for the automatic retrieval of images with coronal loops from the solar image database captured by the SOHO/EIT satellite [1]. Our image retrieval system provides relevant data to astrophysicists who need such data to perform studies that shed light on the mysteries behind solar activities and to analyze the relations between coronal loops and other solar events. As part of ...

We study the evolution of a group of TRACE 195 Å coronal loops overlying a reverse S-shaped filament on 2001 June 15. These loops were initially pushed upward with the filament ascending and kinking slowly, but as soon as the filament rose explosively, they began to contract at a speed of ∼100 km s−1, and sustained for at least 12 min, presumably due to the reduced magnetic pressure underneath ...

A coronal loop can be oscillated in various directions. A basic type of coronal loop oscillation is called transverse oscillation that can be caused by different factors, such as nearby active regions and flares. The damping of transverse oscillation may be produced by the dissipation mechanism or the wake of the traveling disturbance. The aim of this paper is to estimate the damping time of tr...
