Hot DQs, magnetic and metal-polluted white dwarfs: spectroscopic insights from a Gaia machine-learning-selected 500 pc sample
Enrique Miguel GarcÃa Zamora, Santiago Torres Gil, Alberto Rebassa Mansergas +1
The latest Gaia data release provides low-resolution spectra for approximately 100 000 white dwarfs. Though useful for pre-classification, they lack the resolution required for acc…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
White Dwarfs in Wide Binary Systems as Reliable Age Calibrators
Alberto Rebassa-Mansergas, Roberto Raddi, Anna F. Pala +13
Deriving precise stellar ages is a challenging task. Consequently, age-dependent relations - such as the age-metallicity and age-velocity dispersion relations of the Milky Way, or…
The Galactic White Dwarf Population
Santiago Torres, Roberto Raddi, Alberto Rebassa-Mansergas +15
The ESA Gaia mission has revolutionized our understanding of the white dwarf population, delivering an unprecedented census of these nearby remnants and revealing previously unseen…
A Random Forest spectral classification of the Gaia 500-pc white dwarf population
Enrique Miguel GarcÃa Zamora, Santiago Torres Gil, Alberto Rebassa Mansergas +1
The third Gaia Data Release has provided the astronomical community with astrometric data of more than 1.8 billion sources, and low resolution spectra for 220 million. Such a large…
