Accretion Rate Changes Detected in a Polluted White Dwarf
Jay Farihi, Hiba Tu Noor, Carl Melis +6
This letter reports statistically significant changes in the equivalent widths of MgII and CaII lines in the dusty and polluted white dwarf WD 0106-328, based on six epochs of spec…
Discovery of an icy and nitrogen-rich extrasolar planetesimal
Snehalata Sahu, Boris T. Gänsicke, Jamie T. Williams +7
White dwarfs accreting planetary debris provide detailed insight into the bulk composition of rocky exo-planetesimals. However, only one Kuiper-Belt analogue has been identified in…
Measurements of three exo-planetesimal compositions: a planetary core, a chondritic body, and an icy Kuiper belt analogue
Jamie T. Williams, Boris T. Gänsicke, Snehalata Sahu +6
The study of planetesimal debris accreted by white dwarfs offers unique insights into the composition of exoplanets. Using far-ultraviolet and optical spectroscopy, we have analyse…
