In this study, we employ a thermal model to investigate the centrality dependence of the thermal properties of the medium formed during dFormula: see textAu collisions at chemical freeze-out. We analyze published data on various hadron species at mid-rapidity (Formula: see textFormula: see text 0.1) from centrality 0-20%, 20-40%, and 40-100% in d+Au collisions at Formula: see text = 200 GeV, obtained from the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). We focus on determining the thermal properties, specifically the chemical freeze-out temperature (Formula: see text), baryon chemical potential (Formula: see text), and strangeness chemical potential (Formula: see text). To achieve this, we utilize a Formula: see text minimization technique. We then compare the particle ratios derived from the thermal model with the available experimental data. The model successfully describes the particle ratios within ±5 standard deviations. Additionally, we explore system size dependence of the thermodynamic properties of the medium at freeze-out.
