Two families of comets falling onto Beta PIctoris

We have analyzed Ca II H & K absorptions in β Pictoris obtained with the 1.0- metre telescope at the University of Canterbury Mt John Observatory, New Zealand. Our data show a clear division of the exocomets into the two families identified by Kiefer et al. (2014).enTwo families of comets falling onto Beta PIctorisTwo families of comets falling onto B PictorisConference Contributions - Other2018-02-27Fields of Research::51 - Physical sciences::5101 - Astronomical sciences::510109 - Stellar astronomy and planetary systems
