The range of primary mass is dictated by evolutionary considerations, such as the evolutionary tracks of Dorman et al. A search for double-degenerate stars that could progress toward such an outcome remains unfulfilled with most binaries either too lean or too wide SPY program, see Napiwotzki et al. P89 folded on the photometric-based ephemeris Equation 1 compared to the predicted radial velocity curve full line.

We employed grism No. Syntax of coordinates is: The orbital period is the shortest known to date for such systems. It depends mostly on the precision or quality of the coordinates SIMBAD and VizieR catalogs , the resolution of the images from which the sources were extracted, source extent, and source crowding.
