Notes. Radii, luminosities, effective temperatures, and average surface magnetic field strengths are taken from Perraut et al. (2020) and references therein except where specified otherwise. The large frequency separations are derived from the literature following the description given in the text (see Sects. 2.2 and 4.4).
We searched for pulsations in TESS data (see Sect. 2.2).
e.g., Kreidl & Nelson (1990).
(Sikora et al. 2019, and references therein). The values listed correspond to 0.69 × Bd, Bd being the dipolar field.
(Netopil et al. 2017, and references therein).
No rotation period listed in the literature. Furthermore, 54 days of TESS data do not show any rotational variability (see Sect. 2.2).
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.
