Abstract:
beta Pictoris is an A-type star that hosts a complex planetary system
with two massive gas giants and a prominent debris
disc. Variable absorption lines in its stellar spectrum have been
interpreted as signatures of exocomets-comet-like bodies transiting
the star. Stellar flybys can gravitationally perturb objects in the
outer comet reservoir, altering their orbits and potentially injecting
them into the inner system, thereby triggering exocomet showers.
We assessed the contribution of stellar flybys to the observed
exocomet activity by reconstructing the stellar encounter history of
β Pictoris in the past and future.
We used Gaia DR3 data, supplemented with radial velocities from
complementary spectroscopic surveys, to compile a catalogue of stars
currently within 80pc of β Pictoris. Their orbits were
integrated backwards and forwards in time in an axisymmetric Galactic
potential (via the Gala package) to identify encounters within 2pc of
the system.
We identified 99 416 stars currently within 80pc of β Pictoris
with resolved kinematics. Among these, 49 stars (including the eight
components of five binaries) encounter β Pictoris within 2pc
between -1.5Myr and +2Myr. For four of the binaries, the
centre-of-mass trajectories also pass within 2pc. We estimated the
sample to be more than 60% complete within 0.5Myr of today.
Despite β Pictoris being the eponym of its famous moving group,
none of the identified encounters involved its moving group members;
all are unrelated field stars. We found no encounter capable of
shaping the observed disc structures, although stellar flybys may
contribute to the long-term evolution of an Oort Cloud-like structure.
Our catalogue constitutes the most complete
reconstruction of the beta Pictoris encounter history to date and
provides a robust foundation for future dynamical simulations.
Description:
Data for the initial sample of 99416 stars within 80pc of Beta
Pictoris. Sources come form the Gaia Catalogue of Nearby Stars (GCNS)
and the astrometry from Gaia DR3 tables.
Radial velocities were sourced from Gaia DR3, GALAH DR4, RAVE DR6,
LAMOST DR10 (low- and medium-resolution surveys), APOGEE DR17, and
other references in SIMBAD from GCNS. The radial velocities were
corrected according Couture et al. (2023ApJ...946....6C 2023ApJ...946....6C) using Mass
and Log(g) data from Gaia DR3, the previous mentioned sources, TESS
