Magnetic field in atypical prominence structures: Bubble, tornado and eruption [PDF]
, 2016 Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions of the cool plasma and magnetism in `atypical' prominences, namely when ...

Are tornado-like magnetic structures able to support solar prominence plasma? [PDF]
, 2015 Recent high-resolution and high-cadence observations have surprisingly suggested that prominence barbs exhibit apparent rotating motions suggestive of a tornado-like structure. Additional evidence has been provided by Doppler measurements.

Hα Doppler shifts in a tornado in the solar corona [PDF]
, 2016 Context. High resolution movies in 193 Å from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamic Observatory (SDO) show apparent rotation in the leg of a prominence observed during a coordinated campaign. Such structures are commonly referred to

Solar Magnetized "Tornadoes": Relation to Filaments
, 2012 Solar magnetized "tornadoes", a phenomenon discovered in the solar atmosphere, appear as tornado-like structures in the corona but root in the photosphere.
