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…
The redshifted network contrast of transition region emission
W. Curdt, H. Tian, B. N. Dwivedi +1
Aims: We study the VUV emission of the quiet Sun and the net redshift of transition region lines in the SUMER spectral range. We aim at establishing a link with atmospheric process…
