Notes. In the last two columns, we show the limb-darkened angular diameter of the stars extracted from the literature and its references. (G) Values extracted from Gaia Data Release 3 (Gaia Collaboration 2023). (S) Values extracted from SIMBAD. (*), (†) stars considered and rejected by Salsi et al. 2021 (see Sect. 3.2). 1: Boyajian et al. (2012); 2: Rabus et al. (2019); 3: Ségransan et al. (2003); 4: Schaefer et al. (2018); 5: Berger et al. (2006).
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.
