Context. Gravity darkening (GD) and flattening are important consequences of stellar rotation. The precise characterization of these effects across the Hertzsprung–Russell (H-R) diagram is crucial to a deeper understanding of stellar structure and evolution.Aims. We seek to characterize such important effects on Sargas (θ Scorpii), an evolved,...

Context. The interpretation of stellar apparent fundamental parameters (viewing-angle dependent) requires that they be treated consistently with the characteristics of their surface rotation law.Aims. We aim to develop a model to determine the distribution of the effective temperature and gravity, which explicitly depend on the surface...
