Exocomet signatures around the A-shell star φ Leonis?

We present an intensive monitoring of high-resolution spectra of the Ca II K line in the A7IV shell star phi Leo at very short (minutes, hours), short (night to night), and medium (weeks, months) timescales. The spectra show remarkable variable absorptions on timescales of hours, days, and months. T...
