Line Asymmetries in Late-Type Dwarf Photospheres
We have begun a program to observe photospheric line asymmetries in late-type dwarfs. Analysis of spectral line profiles of 61 Cyg A suggests that the combination of line blends and the line asymmetry may give rise to false magnetic field detection. The effects of rotational velocity and excitation potential on line asymmetry are shown for several stars.
