This review chapter for young researchers presents our current understanding of debris discs. It introduces some of their basic properties and observables, and describes how we think they form and collisionally evolve. Special emphasis is dedicated to ALMA observations of the dust and gas, which constrains the distribution of planetesimals, their volatile composition, and potential volatile delivery to planetary atmospheres.

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk
Fomalhaut's debris ring has a forced eccentricity that falls with semi-major axis as a^-1.75 +/- 0.16, the first reported eccentricity gradient in a debris disk.

Silicate mineralogy and bulk composition of exoplanetary material in polluted white dwarfs
New ultraviolet abundances for two white dwarfs, combined with a re-analysis of eight systems, support a tentative correlation between the Mg/Si ratio of accreted exoplanetary material and whether its dust is olivine-...

Resupplying planetary debris to old white dwarfs with supernova blast waves
Supernova blast waves can resupply planetary debris to old white dwarfs by kicking exo-Oort cloud material inward, with metre-sized boulders delivered at least once over a cooling age.
