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 stella…
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…
Population of excited levels of Fe+, Ni+ and Cr+ in exocomets gaseous tails
T. Vrignaud, A. Lecavelier des Etangs
The star Beta Pic is widely known for harbouring a large population of exocomets, which create variable absorption signatures in the stellar spectrum as they transit the star. Whil…
The ANTARESS workflow I. Optimal extraction of spatially resolved stellar spectra with high-resolution transit spectroscopy
V. Bourrier, J. -B. Delisle, C. Lovis +17
High-resolution spectrographs open a detailed window onto the atmospheres of stars and planets. As the number of systems observed with different instruments grows, it is crucial to…
Curves of growth for transiting exocomets: Application to Fe II lines in the Beta Pictoris system
T. Vrignaud, A. Lecavelier des Etangs, F. Kiefer +4
This study introduces the exocomet curve of growth, a new method to analyse the variable absorptions observed in Pictoris spectrum and link them to the physical properties of t…
DREAM I. Orbital architecture orrery
V. Bourrier, O. Attia, M. Mallonn +28
The distribution of close-in exoplanets is shaped by a complex interplay between atmospheric and dynamical processes. The Desert-Rim Exoplanets Atmosphere and Migration (DREAM) pro…
