Chasing Dark Matter in an Ancient Star Cluster: New Limits on Axions from White Dwarf Cooling in 47 Tucanae Can Dying Stars Reveal New Fundamental Particles? Astronomers often use telescopes to study stars, galaxies, and black holes. But sometimes the most profound discoveries emerge not from what we see, but from what appears to be …
Science advances not only through discoveries but also through mysteries. In a recent paper, Investigating the Observational Progenitor Mass Gap in the White Dwarf Initial-Final Mass Relation, we explore an unexpected deficiency of white dwarfs originating from stars within a particular progenitor mass range. Previous studies hinted at a gap in the Initial-Final Mass Relation, …

Some of the oldest stars in our Galaxy reside in globular clusters, and among the most useful members of these stellar cities are white dwarfs. In our latest work, The Cooling of Old White Dwarfs in 47 Tucanae, we examine the faintest white dwarfs in the famous globular cluster 47 Tucanae. These stellar remnants gradually …

How is our understanding of astrophysical phenomena connected with our understanding of fundamental physics?
