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…

Transit distances and composition of low-velocity exocomets in the Pic system
Théo Vrignaud, Alain Lecavelier des Etangs
Pictoris is a young nearby A5V star, about 20 Myr old, embedded in a prominent debris disc. For the past 40 years, variable absorption features have been observed in the stell…

Abundances of refractory ions in Beta Pictoris exocomets
T. Vrignaud, A. Lecavelier des Etangs, P. A. Strom +1
Beta Pic is a young, A5V star, known for harbouring a large number of exocomets, which frequently transit the star and produce absorption signatures. The physical and chemical prop…
