It has long been suspected that metal-polluted white dwarfs (types DAZ, DBZ, and DZ) and white dwarfs with dusty disks possess planetary systems, but a specific physical mechanism by which planetesimals are perturbed close to a white dwarf has not yet been fully posited. In this paper, we demonstrate that mass loss from a central star during post-main-sequence evolution can sweep planetesimals into interior mean motion resonances with a single giant planet. These planetesimals are slowly… 
Short-term stability of particles in the WD J0914+1914 white dwarf planetary system
Nearly all known white dwarf planetary systems contain detectable rocky debris in the stellar photosphere. A glaring exception is the young and still evolving white dwarf WD J0914+1914, which instead
Orbital relaxation and excitation of planets tidally interacting with white dwarfs
Observational evidence of white dwarf planetary systems is dominated by the remains of exo-asteroids through accreted metals, debris discs, and orbiting planetesimals. However, exo-planets in these
Unstable low-mass planetary systems as drivers of white dwarf pollution
At least 25 percent of white dwarfs show atmospheric pollution by metals, sometimes accompanied by detectable circumstellar dust/gas discs or (in the case of WD 1145+017) transiting disintegrating
A power-law decay evolution scenario for polluted single white dwarfs
Planetary systems can survive stellar evolution, as is clear from the atmospheric metal pollution and circumstellar dusty disks of single white dwarfs1,2. Recent observations show that 1−4% of single
Dynamical evolution of two-planet systems and its connection with white dwarf atmospheric pollution
Asteroid material is detected in white dwarfs (WDs) as atmospheric pollution by metals, in the form of gas/dust discs, or in photometric transits. Within the current paradigm, minor bodies need to be
Understanding the origin of white dwarf atmospheric pollution by dynamical simulations based on detected three-planet systems
Between 25-50 % of white dwarfs (WD) present atmospheric pollution by metals, mainly by rocky material, which has been detected as gas/dust discs, or in the form of photometric transits in some WDs.
A 3 Gyr White Dwarf with Warm Dust Discovered via the Backyard Worlds: Planet 9 Citizen Science Project
Infrared excesses due to dusty disks have been observed orbiting white dwarfs with effective temperatures between 7200 and 25,000 K, suggesting that the rate of tidal disruption of minor bodies
Planetary engulfment as a trigger for white dwarf pollution
The presence of a planetary system can shield a planetesimal disk from the secular gravitational perturbations due to distant outer massive objects (planets or stellar companions). As the host star
The frequency and infrared brightness of circumstellar discs at white dwarfs
White dwarfs whose atmospheres are polluted by terrestrial-like planetary debris have become a powerful and unique tool to study evolved planetary systems. This paper presents results for an unbiased
How Sublimation Delays the Onset of Dusty Debris Disk Formation around White Dwarf Stars
Although numerous white dwarf stars host dusty debris disks, the temperature distribution of these stars differs significantly from the white dwarf population as a whole. Dusty debris disks exist

The presence of planets around solar-type stars suggests that many white dwarfs should have relic planetary systems. While planets closer than ~5 AU will most likely not survive the

TLDR
A metal-rich gas disk around a moderately hot and young white dwarf implies that planetary systems may form around high-mass stars.
