BOSS hot subdwarfs — rejected composite candidates

← the survey  ·  confirmed composites  ·  published sdB+dM  ·  candidates  ·  rejected  ·  single stars

Every system the published class, the automatic classifier, or the survey notes call a composite, and whose two-component SED fit rejected it -- tested and settled, the opposite of the still-open list on candidates.html. A blank T₂/M₂ here is the point: no companion temperature the fit would stand behind. Of the 26 here, 26 have a drawable fit.

M₂ is a rough estimate from the fitted radius alone, via the ZAMS mass-radius relation for M < 1.66 M☉ (Demircan & Kahraman 1991) — not a measurement, and only as good as the assumption that the companion sits on the main sequence.
