The nature of the embedded population in the Rho Ophiuchi dark cloud - Mid-infrared observations
Abstract
The authors present results of mid-infrared (primarily 10 and 20 μm wavelength) observations of previously identified members of the embedded populatin of the ρ Ophiuchi dark cloud. These observations enable determination of broad-band energy distributions for 32 of the 44 sources known to be embedded in the cloud. The majority of the sources emit the bulk of their luminosity between 1 μm and 20 μm. These sources apparently are surrounded by dust shells and are probably pre-main-sequence in nature. It is found that the embedded cluster is predominantly composed of low-luminosity objects with luminosities in the range 0.1 ≤ L/L_sun; ≤ 25. When corrected for observational selection effects, the resulting luminosity function appears to be deficient in intermediate-luminosity stars compared with the luminosity function for field stars.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
