Chlorine (Cl) is a chemical element of the group of the halogens and is between the 17th and the 20th most abundant elements in the Solar System. It is thought to be produced from the capture of a proton or neutron by specific alpha-element isotopes during both hydrostatic and explosive oxygen burning, though some contribution may come from Type Ia

Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary systems accreting material onto their surfaces. To detect metallic WDs, we propose a methodology based on an unsupervised learning technique known as Self-Organizing Maps (SOM). This approach

The observation and interpretation of the universe in general have played a major role in cultures from different times and epochs. Studying this role is the main goal of a discipline called "cultural astronomy" or "astronomy in culture". With a tradition of more than three decades, it is an interdiscipline halfway between astronomy and social
