White Dwarf Classification of DESI DR1 Spectra1
This paper presents a new catalog of spectroscopically confirmed white dwarfs from DESI DR1, including atmospheric parameters for over 29,000 DA white dwarfs and 547 magnetic white dwarfs, while demonstrating that magnetic fields likely originate before stellar crystallization and that magnetic white dwarfs are systematically more massive than their non-magnetic counterparts, noting that 'double trouble' systems are not limited to two white dwarfs orbiting each other but sometimes involve a Main Sequence star as the companion.
