Notes. (0) This work; (1) González Hernández et al. (2024).
The expected radius, transit depth, and transit width were naïvely computed under two assumptions: (i) that Barnard b follows the mass-radius relation provided by Parviainen et al. (2024) and (ii) that the impact parameter follows the uniform distribution 𝒰(0, 1). Reported uncertainties reflect the 16th and the 84th percentiles. Some uncertainties are given in parentheses, to the order of the least significant figure.
