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…
Observation of High-speed Outflow on Plume-like Structures of the Quiet Sun and Coronal Holes with SDO/AIA
Hui Tian, Scott W. McIntosh, Shadia Rifal Habbal +1
Observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) reveal ubiquitous episodic outflows (jets) with an average speed around 120 km…
The Spectroscopic Signature of Quasi-periodic Upflows in Active Region Timeseries
Hui Tian, Scott W. McIntosh, Bart De Pontieu
Quasi-periodic propagating disturbances are frequently observed in coronal intensity image sequences. These disturbances have historically been interpreted as being the signature o…
Emission heights of coronal bright points on Fe XII radiance map
H. Tian, C. -Y. Tu, J. -S. He +1
We study the emission heights of the coronal bright points (BPs) above the photosphere in the bipolar magnetic loops that are apparently associated with them. As BPs are seen in pr…
Solar transition region above sunspots
H. Tian, W. Curdt, L. Teriaca +2
We study the TR properties above sunspots and the surrounding plage regions, by analyzing several sunspot spectra obtained by SUMER in March 1999 and November 2006. We compare the…
Hydrogen Lyman-alpha and Lyman-beta spectral radiance profiles in the quiet Sun
H. Tian, W. Curdt, E. Marsch +1
We extend earlier work by studying in the quiet Sun the line profiles of the hydrogen Lyman-alpha and Lyman-beta lines, which were obtained quasi-simultaneously in a raster scan ne…
