    Exploration of long-period oscillations in an H alpha prominence

  • Original language description

    The aim of the present work is to assemble the two sequences of H alpha observations as a full data set lasting two hours to confirm the existence of oscillations, and determine their nature. After having coaligned the Doppler maps of the two sequences, we use a Scargle periodogram analysis and cosine fitting to compute the periods and the phase of the oscillations in the full data set. We conclude that the prominence does not oscillate as a whole structure but exhibits different areas with their own oscillation periods and characteristics: standing or propagating waves. We discuss the nature of the standing oscillations and the propagating waves. These can be interpreted in terms of gravito-acoustic modes and magnetosonic waves, respectively.
