Researchers have developed Solar-CDC, a self-supervised contrastive deep clustering framework designed to analyze solar wind data. This novel approach utilizes a Transformer encoder and a triplet margin loss to map plasma observables into a latent space, aiming to resolve the long-standing question of whether the slow solar wind originates from one or two distinct coronal sources. The framework demonstrated superior performance compared to traditional dimensionality reduction and clustering methods, achieving a silhouette score of 0.869 on over 30,000 Solar Orbiter observations, and successfully identified distinct populations based on heavy-ion composition, even when this data was withheld from the model.
