Connecting planetary systems at different stages of stellar evolution helps
us understand their formation, evolution, and fate, and provides us with
exclusive and crucial insights about their dynamics and chemistry.
Post-main-sequence white dwarf and giant branch stars host planetary systems
that include a variety of observed objects and phenomena, such as planetary
debris discs, disintegrating and embedded asteroids, and photospheric metal
pollution. Here, I provide a review of both our current knowledge of these
systems and models which have been used to explain them. I also highlight
the transformative advances expected in upcoming years with the current and
next generation of ground-based and space-based initiatives. Looming
orders-of-magnitude increases in available data must be accompanied by novel
theories and simulations in order to understand the results from this
interdisciplinary and expanding research field.
