Exocomets of Beta Pictoris I: Exocomet destruction, sodium and disk line variability in 17 years of HARPS observations - Astrobiology
The young β Pictoris system has been monitored with high-resolution optical spectrographs for decades. These observations have revealed strongly variable absorption in the Ca II H\&K lines attributed to in-falling cometary bodies. Since 2003, over 9000 HARPS observations of β Pictoris have been taken and many of these have not yet been used for exocomet […] The post Exocomets of Beta Pictoris I: Exocomet destruction, sodium and disk line variabi…
