Extended Data Figure 4: Results of the statistical analysis carried out in parameter space about the optimal seismic model for KIC08626021.
From: A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf
Only the most interesting parameters are illustrated here. Each histogram shows the derived probability-density function for a given model parameter. The orange hatched region between the two vertical solid red lines defines the?±1σ range, containing 68.3% of the distribution. The green curve defines the Gaussian fit applied to the distribution, which gives the?±1σ range. The blue vertical dashed line indicates the value of the parameter of the optimal model solution. The mean, median and mode values are also indicated. The estimate of the parameter of interest, indicated in red, is the statistical value (not the optimal one) and corresponds to the central value of the?±1σ interval. The various panels correspond to the following model parameters: a, effective temperature; b, surface gravity; c, central mass fraction of oxygen; d, total mass fraction of helium; e, total mass; and f, total radius of the star (in logarithmic units).
