High spatial resolution observations of some solar photospheric line profiles. Hanslmeier, A., Mattig, W., & Nesis, A. Astronomy and Astrophysics, 238:354–362, EDP, November, 1990.
Paper abstract bibtex Results are presented of high resolution spectroscopic solar granulation observations with the Gregory Coude Telescope at Izana (Tenerife) in photospheric nonactive regions. Line asymmetries of four Fe I lines were analyzed depending on their origination in granular or intergranular regions. With the increased spatial resolution, instead of the classical C-shape, red line asymmetries are found in the intergranulum and blue line asymmetries in the granulum. Correlations between various line parameters such as continuum intensity, line center velocity, and equivalent width were examined. The results are in agreement with theoretical model calculations.
