DOI: 10.1093/mnras/staa2608

Abstract: Debris discs are second-generation dusty discs formed by collisions of planetesimals. Many debris discs have been found and resolved around hot and solar-type stars. However, only a handful have been discovered around M-stars, and the… read more here.

DOI: 10.1093/mnras/stad1221

Abstract: The radial structure of debris discs can encode important information about their dynamical and collisional history. In this paper we present a 3-phase analytical model to analyse the collisional evolution of solids in debris discs,… read more here.

DOI: 10.1093/mnras/stae1923

Abstract: Water ice plays a crucial role throughout the different stages of planetary evolution and is abundant in the Universe. However, its presence and nature in debris discs of exoplanetary systems are not yet strongly established… read more here.

DOI: 10.1093/mnras/staf1555

Abstract: Debris discs provide valuable insights into the formation and evolution of exoplanetary systems. Their structures are commonly attributed to planetary perturbations, serving as probes of as-yet-undetected planets. However, most studies of planet-debris disc interactions ignore… read more here.

DOI: 10.1093/mnras/sty1724

Abstract: Debris disks are second generation dusty disks thought to be devoid of gas. However, this idea has been challenged in the last years by gas detections in some systems. We compiled a database of 301… read more here.

DOI: 10.1093/mnras/stz1496

Abstract: Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently studied. In this paper we present the main metallicity… read more here.
