Identification of (m, ṁ, r, α) values resulting in an enrichment of ¹⁴N, ²⁷Al, and ³⁹K larger than two (ξ = 2, left panel), and greater than four (ξ = 4, right panel). The size of the points corresponds to the distance to the center of the black hole, r. Only 20 (upper-left), 82 (middle-left), and 6 (lower-left) out of the 25 730 points enable an enrichment by a factor of 2, translating into 0.07%, 0.3%, and 0.02% cases of enrichment. When ξ = 4, the number of points becomes 6 (upper-right), 19 (middle-right), and 4 (lower-right), translating into 0.02%, 0.07%, and 0.015% case of enrichment. The largest distance to the black hole making an enrichment possible occurs for a value of r = 61r_sch, visible in the upper and middle left panels.
