We make use of a new hybrid method to simulate the long-term, multiple-orbit disc formation
through tidal disruptions of rocky bodies by white dwarfs, at high-resolution and realistic …

White dwarf (WD) pollution is thought to arise from the tidal disruption of planetary bodies.
The initial fragment stream is extremely eccentric, while observational evidence suggest that …

We analyse how drag forces modify the orbits of objects moving through extended gaseous
distributions. We consider how hydrodynamic (surface area) drag forces and dynamical …

The discovery of the intact minor planet embedded in the debris disc orbiting SDSS J1228+
1040 raises questions about the dynamical history of the system. Further, the recent …

We simulate the passage through the Sun–Jupiter system of interstellar objects (ISOs)
similar to 1I/'Oumuamua or 2I/Borisov. Capture of such objects is rare and overwhelmingly …

Aeolian erosion is a destructive process that can erode small-size planetary objects through
their interaction with a gaseous environment. Aeolian erosion operates in a wide range of …

We investigate the trapping of interstellar objects during the early stages of star and planet
formation. Our results show a very wide range of possible values that will be narrowed down …

Escalating observations of exo-minor planets and their destroyed remnants both passing
through the Solar system and within white dwarf planetary systems motivate an …

Since 2017, two macroscopic interstellar objects have been discovered in the inner Solar
System, both of which are distinct in nature. The first interstellar object, 1I/'Oumuamua …

In this chapter we review our knowledge of our galaxy's cometary population outside our
Oort Cloud-exocomets and Interstellar Objects (ISOs). We start with a brief overview of …
