Wave Period Variability in a Quiescent Solar Prominence


ABSTRAKT / ABSTRACT :

On 26 September 2022, we observed a quiescent solar prominence
with Hα imaging spectroscopy using the Solar Dynamics Doppler
Imager (SDDI) on the SMART telescope. Unlike earlier works
that detected 4- and 15-min oscillations through long-slit,
1D wavelet methods, we adapt the wavelet analysis to 3D data
to explore the full prominence structure. Complementary data
from SDO/AIA (304 ̊A, 171 ̊A) STEREO-A/EUVI (304 ̊A), and Solar
Orbiter EUI/FSI (304 ̊A, 174 ̊A) enable a multi-view,
multi-thermal investigation of wave periodicity across the
prominence. Our aim is to characterize how oscillatory periods
are distributed in plasma at different temperatures and
viewing angles, thereby assessing wave propagation and
variability throughout the prominence body.
