Wave Propagation and Jet Formation in the Chromosphere
L. Heggland, V. H. Hansteen, B. De Pontieu +1
We present the results of numerical simulations of wave propagation and jet formation in solar atmosphere models with different magnetic field configurations. The presence in the c…
Forward modeling of emission in SDO/AIA passbands from dynamic 3D simulations
Juan Martinez-Sykora, Bart De Pontieu, Paola Testa +1
It is typically assumed that emission in the passbands of the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) is dominated by single or several stro…
Propagating waves along spicules
Takenori J. Okamoto, Bart De Pontieu
Alfvénic waves are thought to play an important role in coronal heating and acceleration of solar wind. Here we investigated the statistical properties of Alfvénic waves along spic…
Direct Imaging by SDO AIA of Quasi-periodic Fast Propagating Waves of ~2000 km/s in the Low Solar Corona
Wei Liu, Alan M. Title, Junwei Zhao +5
Quasi-periodic, propagating fast mode magnetosonic waves in the corona were difficult to observe in the past due to relatively low instrument cadences. We report here evidence of s…
Two components of the coronal emission revealed by EUV spectroscopic observations
Hui Tian, Scott W. McIntosh, Bart De Pontieu +3
Recent spectroscopic observations have revealed the ubiquitous presence of blueward asymmetries of emission lines formed in the solar corona and transition region. These asymmetrie…
