Modeling of exocomet orbits in β Pictoris system
Abstract
Observational features of spectral absorption lines of Ca II towards the β Pictoris star are associated with exocomets activity in the vicinity of this star. These features are the distortions of the stellar profile of the Ca II absorption line caused by eclipses of falling evaporating bodies (FEBs). Two exocomet families with different radial velocities have been distinguished previously: family "S" with V r = 36 ± 55 km/s and family "D" with V r = 15 ± 6 km/s. The purpose of this work is to find and study the orbits of exocomets that can be associated with the family "D". The obtained results suggest that the parameters of the orbits vary widely. In particular, there are orbits that are close to circular, and at the same time there are orbits with high eccentricities.
