Exocomets: A study of the gaseous environment of A-type main sequence stars
2020
Zenodo
In main sequence stars, infrared excesses attributed to the presence of circumstellar dust in debris discs has been the empirical indirect probe of the existence of minor bodies for more than 40 years, as they were needed to explain the dust emission. But it was not until 1987 that the first evidence of the presence of exocomets was found. It was around the Beta Pictoris star and it came with the detection of non-photospheric variable absorptions superimposed to the photospheric Ca II lines.
