Notes. The radius R is from FLAME. The column labelled ΔG gives a proxy of the variability in the G band (see text). The column labelled Plpv lists the period obtained by the photometric analysis (table vari_long_period_variable), whereas Pnss corresponds to the period of the SB1 orbit.

(a)

Limb-darkened diameter of 0.393 mas from Cruzalèbes et al. (2019), or 96 R⊙ with parallax ϖ = 0.44 mas.

(b)

Limb-darkened diameter of 0.672 mas from Cruzalèbes et al. (2019), or 106 R⊙ with parallax ϖ = 0.68 mas.

(c)

Since Pnss = Plpv, the RV variations are due to atmospheric pulsations rather than to orbital motion.

(d)

Also CGCS 396 in the General Catalog of Cool Galactic Carbon Stars, flagged as Mira variable.

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.
