Mass distributions in the Local Bubble. Left: mass distributions of hydrogen (black; left axis), and ²⁶Al (red) and ⁶⁰Fe (blue; both isotopes right axis) as a function of n_H in the hydrodynamics simulation by Schulreich et al. (2023). Note that the right axis is scaled by 10⁻⁹ to the left axis to allow a visual comparison. Right: cumulative distribution of the hydrogen, ²⁶Al and ⁶⁰Fe masses from the left panel with maximum (total) masses of 3.5 × 10⁵ M_⊙, 1.6 × 10⁻⁵ M_⊙ and 4.9 × 10⁻⁴ M_⊙, respectively. Only cells for which the flow speed is higher than 1 km s⁻¹ are used to ensure that the static background medium is not considered as part of the Local Bubble.
