Instability Due to Electron Captures of Nuclei ⁵⁶Ni, ⁵⁶Co, ⁵⁶Fe, ⁵⁶Mn, ⁵⁶Cr, and ⁵⁶V in Strongly Magnetized Super-Chandrasekhar White Dwarfs

Based on the theory of relativistic mean-field effective interactions, we explore effect superstrong magnetic fields (SMFs) nuclear single-particle level structure, blinding energy, and electron Fermi energy in strongly magnetized super-Chandrasekhar white dwarfs (SMSWDs). We also discuss capture (EC) instability from threshold mass density (TMD) pressure (TP) for some typical iron group nuclei SMSWD due to SMFs. At relatively low densities (e.g., ρ7 = 57, 97, 197), EC rates increase they then decrease by more than four orders magnitude. However, at higher 4197), about two magnitude when 2 × 103 < B12 5 104, SMFs have a minor rates. The TMD can 23% ∼ 29%, an electron–ion interaction binding As further increase, almost linearly one Landau levels system. For three system, slight influence 103.5), increases 13% 14%, finally decreases 27.85% (27.34%). shift onset make maximum 2.28% This be larger that general relativity SMSWD, which contains nuclei.
