Multiresolution wavelet analysis of SUMER/SOHO observations in a solar prominence

Mostrar otras versiones (2)

We have studied through a multiresolution wavelet analysis the oscillations in a limb prominence. Intensity fluctuations in time and height corresponding to different lines of Si IV and O IV observed with SUMER on board SOHO have been analyzed in the wavelet bands of J3 = 1 min 36 s to 3 min 12 s an...

520 3 |a We have studied through a multiresolution wavelet analysis the oscillations in a limb prominence. Intensity fluctuations in time and height corresponding to different lines of Si IV and O IV observed with SUMER on board SOHO have been analyzed in the wavelet bands of J3 = 1 min 36 s to 3 min 12 s and J4 = 3 min 12 s to 6 min 24 s. For all species, oscillations in the J4 band were dominant. We found relevant differences between the behavior of line D1 (1393.76 Å) corresponding to Si IV and the set D2 (1401.16 Å), D3 (1404.81 Å), D4 (1402.77 Å) corresponding to O IV, O IV and Si IV respectively. We also report the identification of a pulse in the intensity of the line D1 that appears in the range of 15-20 min. This disturbance seems to travel with a speed of about 170 km s-1.  |l eng
