The evolution of exocomets and their source populations
Alexander J. Mustill, Tim Pearce, Michele Bannister +12
We review the current state of knowledge of the long-term evolution of the small bodies that give rise to comets and exocomets, as well as their reservoirs. The active cometary pha…
Exocometary physics: material release and tails
Théo Vrignaud, Dennis Bodewits, Jake Hanlon +5
Despite decades of observations, the physical processes governing mass loss from small bodies beyond our Solar System remain poorly constrained. These exocomets are often treated a…
HD 44892: The youngest (or oldest?) gas-harbouring debris disc around an intermediate mass star
Karolina M. Szewczyk, Olja PaniÄ, Daniela P. Iglesias +2
We present the first detections of gas around a 2.1 Myr old debris disc-bearing intermediate-mass star, HD 44892. Gas is detected both in CO (2-1) emission through ALMA Band…
Dust populations from 30 to 1000 au in the debris disk of HD 120326
C. Desgrange, J. Milli, G. Chauvin +15
Context. To date, more than a hundred debris disks have been spatially resolved. Among them, the young system HD 120326 stands out, displaying different disk substructures on both…
