    Applying the Adomian Method to Solve the Fokker–Planck Equation: A Case Study in Astrophysics by Melina Silva de Lima, José Vicente Cardoso Santos, José Humberto de Souza Prates, Celso Barreto Silva, Davidson Moreira, Marcelo A. Moret

    Published 2024-10-01
    “…Adjustments in the parameter α (related to the order of fractional temporal derivation) reveal the extent of the memory effect, strongly correlating with fractal properties in the diffusive process. Extending this research to other XRBs is both possible and recommended to generalize the characteristics of X-ray scattering and electromagnetic waves at different frequencies originating from similar astronomical objects.…”
