Published in 2017 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/201730486

Abstract: We proposed that the use of an approximate “jump condition” at the solar transition region permits fast and accurate numerical solutions of the one dimensional hydrodynamic equations when the corona undergoes impulsive heating. In particular,… read more here.

Published in 2021 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab1959

Abstract: The solar photosphere, chromosphere, and corona are known to rotate differentially as a function of latitude. To date, it is unclear whether the solar transition region also rotates differentially. In this work, we investigate the… read more here.
