By December 2025, the Parker Solar Probe (PSP) had completed 26 orbits around the Sun. During this period, the spacecraft encountered numerous slow Alfvénic wind intervals. In this study, we systematically investigate the plasma properties associated with these regions, focusing on how key parameters such as density, temperature, and magnetic field fluctuations evolve with radial distance from the Sun. By analyzing multiple slow Alfvénic wind intervals over a wide range of heliocentric distances, we aim to provide a comprehensive picture of the radial evolution of plasma conditions within the slow Alfvénic wind. This work contributes to a deeper understanding of the origin and evolution of the slow Alfvénic wind.
