logPcyc versus logProt. The solid gray lines represent the actives (Aa and Ab) and inactive (I) branches reported in Böhm-Vitense (2007). We indicate theextrapolation to lower rotation periods with dashed lines. Gray stars represent the activity cycle periods obtained forthe early-M dwarfs Gl 752A (Buccino et al. 2011), AD Leo (Buccino et al. 2014), and AU Mic (Ibañez Bustos et al. 2019a). The red stars represent the periods of Gl 729 we report here.
