Sloan low-mass wide pairs of kinematically equivalent stars (SLoWPoKES): a catalog of very wide, low-mass pairs. Dhital S., West A.A., Stassun K.G., Bochanski J.J. <Astron. J., 139, 2566-2586 (2010)> =2010AJ....139.2566D
ADC_Keywords: Stars, double and multiple ; Photometry, SDSS ; Proper motions Keywords: binaries: general - binaries: visual - brown dwarfs - stars: late-type - stars: low-mass - stars: statistics - subdwarfs - white dwarfs Abstract: We present the Sloan Low-mass Wide Pairs of Kinematically Equivalent Stars (SLoWPoKES), a catalog of 1342 very-wide (projected separation ≳500AU), low-mass (at least one mid-K to mid-M dwarf component) common proper motion pairs identified from astrometry, photometry, and proper motions in the Sloan Digital Sky Survey. A Monte Carlo-based Galactic model is constructed to assess the probability of chance alignment for each pair; only pairs with a probability of chance alignment ≤0.05 are included in the catalog.

Note (1): The identifiers were generated using the standard JHHMM+DD format using coordinates of the primary star. Note (2): All magnitudes are psfmag and have not been corrected for extinction. Note that we use extinction-corrected magnitudes in our analysis. Note (3): Calculated using photometric parallax relations and have 1σ errors of ∼14%. The absolute distances to subdwarfs (SDs) are overestimated (see Section 2.4.1). Note (4): The spectral types were inferred from the r-z colors (West et al. 2008, Cat. J/AJ/135/785; Covey et al. 2007, Cat. J/AJ/134/2398) and are correct to ±1 subtype. Note (5): Type of SLowPoKES pair as follows: DD = Disk dwarf SD = Subdwarf WD = White dwarf-disk dwarf T = Triple

Note (1): We have tried to use HIP and NLTT identifiers, whenever they exist, for consistency. Note (2): Spectral types are from the referenced papers, SIMBAD, or inferred from their V-J colors using Kenyon & Hartmann (1995, Cat. J/ApJS/101/117). Note (3): Binding energies are calculated using estimated masses as a function of spectral type Kraus & Hillenbrand (2007, Cat. J/AJ/134/2340). When spectral type for the secondary was not available, it was assumed to be an equal-mass binary. Note (4): References as follows: 1 = Lepine & Bongiorno (2007, Cat.
