Quantifying spectroscopic Ca II exocomet transit occurrence in two decades of HARPS data
Raphaël Bendahan-West, Grant M. Kennedy, David J. A. Brown +1
The field of exocomets has been built around the unmatched number of detections made in the circumstellar disc of the archetypal star Beta Pictoris. An exocomet detection in spectr…
