Notes. Header: # sp. indicates the number of available spectra, Sp. Var. Type and TESS Var. Type indicate the spectroscopic and photometric variability classifications respectively. We note that the values of logℒ/ℒ⊙ provided in this table have been computed using gravities already corrected for centrifugal acceleration (following the recipe proposed in Herrero et al. 1992 and Repolust et al. 2004). TESS Variability types: EB (eclipsing binary), rot (rotational modulation), SPB (low frequency pulsation modes), β Cep (high frequency pulsation modes), SLF (stochastic low frequency signal), PQ (poor quality data), or cont. (contaminated). A question mark indicates that the TESS light curve is insufficient to disentangle the contribution of g modes, rotation effects and SLF. Spectroscopic Variability types: SB1 or SB2 (single or double lined spectroscopic binary), LPV (line profile variability in photospheric lines), WVa or WVe (Variability of the Hα line in absorption or emission).
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.
