Prominence oscillations activated by an EUV wave

چکیده
Prominence oscillations are one of interesting phenomena in the solar atmosphere, which can be utilized to infer embedded magnetic field magnitude. We present here transverse two different prominences located at East limb on 2011 February 11 using multi-wavebands data Atmospheric Imaging Assembly (AIA) on-board Solar Dynamics Observatory (SDO) satellite. A prominence eruption was observed towards east direction with an average speed ~275 km/s. The is fitted combination a linear and exponential functions time. An extreme ultraviolet (EUV) wave event associated eruption. This EUV triggered both limb. computed period each wavelet analysis method. oscillation varies from 14 22 min. derived, ranges 20 G.

Prominence oscillations and stability
The photosphere provides an important boundary condition for prominence support. The conservation of pho-tospheric flux (sometimes called line tying) sets a serious constraint on the evolution of coronal magnetic fields. This boundary condition can only be communicated to the prominence by Alfvén and magneto-acoustic waves. As a result, the boundary condition as experienced by the prominence at...
متن کاملNumerical simulation of prominence oscillations
We present numerical simulations, obtained with the Versatile Advection Code, of the oscillations of an inverse polarity prominence. The internal prominence equilibrium, the surrounding corona and the inert photosphere are well represented. Gravity and thermodynamics are not taken into account, but it is argued that these are not crucial. The oscillations can be understood in terms of a solid b...
متن کاملEUV lines observed with EIS/Hinode in a solar prominence
Context. During a multi-wavelength observation campaign with Hinode and ground-based instruments, a solar prominence was observed for three consecutive days as it crossed the western limb of the Sun in April 2007. Aims. We report on observations obtained on 26 April 2007 using EIS (Extreme ultraviolet Imaging Spectrometer) on Hinode. They are analysed to provide a qualitative diagnostic of the ...
متن کاملProminence seismology using small amplitude oscillations
Quiescent prominences are thin slabs of cold, dense plasma embedded in the much hotter and rarer solar corona. Although their global shape is rather irregular, they are often characterised by an internal structure consisting of a large number of thin, parallel threads piled together. Prominences often display periodic disturbances mostly observed in the Doppler displacement of spectral lines an...
متن کاملSynthetic hydrogen spectra of prominence oscillations
Context. Prominence oscillations have been mostly detected using Doppler velocity, although there are also claimed detections by means of periodic variations in half-width or line intensity. However, scarce observational evidence exists about simultaneous detection of oscillations in several spectral indicators. Aims. Our main aim here is to explore the relationship between spectral indicators,...
