چکیده

Abstract Here, we study the temperature structure of flaring and non-flaring coronal loops, using extracted loops from images taken in six extreme ultraviolet (EUV) channels recorded by Atmospheric Imaging Assembly (AIA)/ Solar Dynamic Observatory (SDO). We use data for X2.1-class-flaring active region (AR11283) during 22:10UT till 23:00UT, on 2011, September 6; (AR12194) 08:00:00UT 09:00:00UT 2014, October 26. By spatially-synthesized Gaussian DEM forward-fitting method, calculate peak temperatures each strip loops. apply Lomb-Scargle method to compute oscillations periods series strip. The are ranged 7 min 28.4 min. These show very close behavior slow-mode oscillation. observe that started at least around 10 minutes before transverse continue a long time duration even after ended. amplitudes increased (during 20 min) obtained 8.5 30 min,but their significances less (below 0.5) comparison with ones (near one). Hence detected loops' strips probable ones, maybe they just fluctuations. Based our confined observations, it seems more diversity have wider ranges variation than ones. More accurate commentary this respect requires extensive statistical research broader observations.

Dynamic Magnetography of Solar Flaring Loops

We develop a practical forward fitting method based on the SIMPLEX algorithm with shaking, which allows the derivation of the magnetic field and other parameters along a solar flaring loop using microwave imaging spectroscopy of gyrosynchrotron emission. We illustrate the method using a model loop with spatially varying magnetic field, filled with uniform ambient density and an evenly distribut...

Inferring the coronal flaring patterns in AGN from reverberation maps

The relativistically broadened iron K-α line at 6.4 keV observed in the Seyfert 1 galaxy MCG–6-30-15 has provided a probe of the strong-gravity environment near a black hole, in particular suggesting that it is rapidly spinning. An important variable in such analyses is the geometry of the illuminating source. We present a new technique which constrains this geometry based on the spectral line ...

Acoustic oscillations in solar and stellar flaring loops

Evolution of a coronal loop in response to an impulsive energy release is numerically modelled. It is shown that the loop density evolution curves exhibit quasi-periodic perturbations with the periods given approximately by the ratio of the loop length to the average sound speed, associated with the second standing harmonics of an acoustic wave. The density perturbations have a maximum near the...

Evidence of widespread hot plasma in a non-flaring coronal active region from Hinode/XRT

Nanoflares, short and intense heat pulses within spatially unresolved magnetic strands, are now considered a leading candidate to solve the coronal heating problem. However, the frequent occurrence of nanoflares requires that flare-hot plasma be present in the corona at all times. Its detection has proved elusive until now, in part because the intensities are predicted to be very faint. Here we...

ASCA and EUVE observations of II Pegasi: flaring and quiescent coronal emission

We have analyzed X-ray and EUV spectra of both the quiescent and flaring state of II Peg, obtained from observations with ASCA and EUVE. Coronal temperature structure and abundances have been derived from multi-temperature and differential emission measure (DEM) analyses of the spectra. The abundances are non-solar; in the case of ASCA for most elements (O, Ne,Mg, Si, S, Ar, Ca, Ni) we obtain a...
