Abstract:
We present the multiple stellar systems observed within the SpHere
INfrared survey for Exoplanet (SHINE). SHINE searched for substellar
companions to young stars using high contrast imaging. Although stars
with known stellar companions within SPHERE field of view (<5.5arcsec)
were removed from the original target list, we detected additional
stellar companions to 78 of the 463 SHINE targets observed so far. 27%
of the systems have three or more components. Given the heterogeneity
of the sample in terms of observing conditions and strategy, tailored
routines were used for data reduction and analysis, some of which were
specifically designed for these data sets. We then combined SPHERE
data with literature and archival ones, TESS light curves and Gaia
parallaxes and proper motions, to characterise these systems as
completely as possible. Combining all data, we were able to constrain
the orbits of 25 systems. We carefully assessed the completeness of
our sample for the separation range 50-500mas (period range a few
years - a few tens of years), taking into account the initial
selection biases and recovering part of the systems excluded from the
original list due to their multiplicity. This allowed us to compare
the binary frequency for our sample with previous studies and
highlight some interesting trends in the mass ratio and period
distribution. We also found that, for the few objects for which such
estimate was possible, the values of the masses derived from dynamical
arguments were in good agreement with the model predictions. Stellar
and orbital spins appear fairly well aligned for the 12 stars having
enough data, which favour a disk fragmentation origin. Our results
highlight the importance of combining different techniques when
tackling complex problems such as the formation of binaries and show
how large samples can be useful for more than one purpose.
Description:
SHINE is a large direct imaging planet-search survey started at the
VLT in 2015 in the framework of the SPHERE Guaranteed Time
Observations (GTO) carried on by the SPHERE Consortium. The survey
concept and the selection of the sample are described in detail in
Desidera et al. (2021A&A...651A..70D 2021A&A...651A..70D, Cat. J/A+A/651/A70), the
observations and data reduction procedures in Langlois et al.
(2021A&A...651A..71L 2021A&A...651A..71L, cat. J/A+A/651/A71), while the statistical
analysis and inference on planet population from the first 150 stars
(F150 sample) is presented in Vigan et al. (2021A&A...651A..72V 2021A&A...651A..72V).
