A&a Manuscript No. Astronomy and Astrophysics New Insight into Transition Region Dynamics via Sumer Observations and Numerical Modelling

We explore the idea that the occurrence of nano-ares in a magnetic loop around the O vi formation temperature could explain the observed red-shift of mid-low transition region lines as well as the blue-shift observed in low coronal lines (T > 6 10 5 K). Observations are compared to numerical simulations of the response of the solar atmosphere to an energy… CONTINUE READING
