Notes. Luminosity difference, ΔL, between the maximum and minimum radii, Δm bolometric magnitude difference between maximum and minimum radii, P pulsation period, ΔR difference between maximum and minimum radii, maximum velocity achieved during a pulsation cycle, τdyn dynamical timescales, τth thermal timescales, and ωdyn frequency of the pulsations normalized by the dynamical timescale as defined in Glatzel et al. (1993).
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.
