VizieR Online Data Catalog: Stellar multiplicity and debris discs (Rodriguez+, 2015)

The DEBRIS sample consists of 451 stars, of which 2 are not primaries (Fomalhaut B & C; see Mamajek et al. 2013AJ....146..154M; Kennedy et al. 2014MNRAS.438L..96K), and includes the 5 systems observed by the Herschel Guaranteed Time (GT) discs programme (PI: Olofsson).

We present the full list of stars and multiplicity information in Table 1. Some systems have tentative evidence of being astrometric binaries, but no additional information exists to confirm this. These systems are treated as single stars for this study. Binaries and higher multiples are listed with more details in Table 2. In general, we only have measurements of the period of spectroscopic binaries and projected separation for visual binaries.

We have utilized the AO camera IRCAL at Lick Observatory to search for companions separated from the primary by ~10-1000AU.

Tables 4 and 5 list our observations and measured parameters for binary and single stars, respectively.
