Observations of the Sun with ALMA have become a big asset to study the dynamic of the solar chromosphere. In this talk, I will describe the main characteristics of small-scale bright features detected in ALMA Bands 3 (~100 GHz) and 6 (240 GHz) that appear to be associated with MHD modes, one of the phenomena that are thought to significantly contribute to the heating of the solar atmosphere.
Additionally, the height difference between 2 pairs of ALMA sub-bands is also shown and thereafter used to estimate the propagation of waves through the solar chromosphere.
Finally, a first attempt to estimate energy fluxes due to MHD waves with ALMA observations is described.
This Friday colloquium will be hybrid. Attendees can therefore participate either in-person or via Zoom. Please join via Zoom at
