Scientific paper

A spectrum-synthesis analysis of eight spectra obtained during the nonflaring state of the cool dM4e flare star AD Leonis, yielded a mild, consistent underabundance, about 0.4 dex with respect to the sun, for all metals. The turbulence and rotational velocities obtained were consistent with previous studies. If the abundance results are real, the star may be older than commonly thought; however, filling in of the line cores by emission cannot be ruled out.
