Notes. Aside from those determined through our own analysis (i.e. v sin i, u, B_pol), parameters are retrieved from [1] Zwintz et al. (2020), [2] North et al. (1998), [3] Netopil et al. (2017), [4] Escorza et al. (2016), [5] Wraight et al. (2012), [6] Casagrande et al. (2011), [7] Wade et al. (2000), [8] Lampens et al. (2013), [9] Neiner et al. (2017), or alternatively [†] inferred from Gaia (Gaia Collaboration 2023a). The field characterisations shown in the last column correspond to dynamo (D), fossil (F), or as-of-yet unknown (U).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
