We review the properties of dust formed during classical nova eruptions andthe Very Late Thermal Pulses (VLTPs) that occur during the later stages ofpost-Asymptotic Giant Branch evolution of low-mass stars. In both cases, carbonand hydrocarbon dust is produced. Novae may also produce silicate dust,contrary to the usual paradigm about the C:O ratio and dust composition.Despite the expectation that these dust sources are not expected to makesignificant contributions to the Galactic dust population, there is asignificant body of evidence that grains from both stellar sources have beenidentified in recovered meteoritic and cometary material, and that certaininfrared spectral signatures seen in comets are common to novae, VLTPs andpre-solar grains.

Pre-solar grains from novae and "Born-again giants"
