Discovery of a second-generation planet candidate accreting onto a white dwarf
Jamie T. Williams, Boris T. Gänsicke, Nicholas C. Stone +10
Many white dwarfs accrete the debris of disrupted planetary bodies, detected in the form of metal-enrichment in their atmospheres, dusty or gaseous circumstellar discs, and photome…
Planetary Accretion Is Less Frequent in Wide Binaries: Evidence from Metal-Enriched White Dwarfs in DESI DR1
Siyi Xu, Laura. K. Rogers, Joan Najita +32
Binary stars are common in the Galaxy, and understanding how stellar binarity influences the formation and evolution of planetary systems is an active area of research. In this stu…
An irradiated-Jupiter analogue hotter than the Sun
Na'ama Hallakoun, Dan Maoz, Alina G. Istrate +10
Planets orbiting close to hot stars experience intense extreme-ultraviolet radiation, potentially leading to atmosphere evaporation and to thermal dissociation of molecules. Howeve…
Collisions in a gas-rich white dwarf planetary debris disc
Andrew Swan, Scott J. Kenyon, Jay Farihi +5
WD 0145+234 is a white dwarf that is accreting metals from a circumstellar disc of planetary material. It has exhibited a substantial and sustained increase in 3-5 micron flux sinc…
Alkali metals in white dwarf atmospheres as tracers of ancient planetary crusts
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +2
White dwarfs that accrete the debris of tidally disrupted asteroids provide the opportunity to measure the bulk composition of the building blocks, or fragments, of exoplanets. Thi…
GD424 -- a helium-atmosphere white dwarf with a large amount of trace hydrogen in the process of digesting a rocky planetesimal
Paula Izquierdo, Odette Toloza, Boris T. Gänsicke +5
The photospheric metal pollution of white dwarfs is now well-established as the signature of the accretion of planetary debris. However, the origin of the trace hydrogen detected i…
