Close encounters: How stellar flybys shape planet-forming discs

N Cuello, F Ménard, DJ Price - The European Physical Journal Plus, 2023 - Springer
We review the role of stellar flybys and encounters in shaping planet-forming discs around
young stars, based on the published literature on this topic in the last 30 years. Since most …

On the frequencies of circumbinary discs in protostellar systems

D Elsender, MR Bate, BS Lakeland… - Monthly Notices of …, 2023 - academic.oup.com

Observations of planet forming disks in multiple stellar systems

A Zurlo, R Gratton, S Pérez, L Cieza - The European Physical Journal Plus, 2023 - Springer
The demographic of circumstellar disks, the birthplaces of planets, is diverse and rich in
disks featuring rings, gaps, spirals, filaments, and arcs. Many studies revealing these disk …
