Investigating Disk Evolution: A High Spatial Resolution Mid‐Infrared Survey of T Tauri Stars
Open accessAbstract
We present a high spatial resolution, 10-20 μm survey of 65 T Tauri binary stars in Taurus, Ophiuchus, and Corona Australis using the Keck 10 m telescopes. Designed to probe the inner ~1 AU region of the circumstellar disks around the individual stellar components in these binary systems, this study increases the number of binaries with spatially resolved measurements at 10 μm by a factor of ~5. Combined with resolved near-infrared photometry and spectroscopic accretion diagnostics, we find that ~10% of stars with a mid-infrared excess do not appear to be accreting. In contrast to an actively accreting disk system, these passive disks have significantly lower near-infrared colors that are, in most cases, consistent with photospheric emission, suggesting the presence of an inner disk hole. In addition, there appears to be a spectral type/mass dependence associated with the presence of a passive disk, with all passive disks occurring around M-type stars. The presence of a passive disk does not appear to be related to the fact that these objects are in visual binary systems; the passive disk systems span the entire range of binary separations present in the sample, and a similar fraction of passive disks is observed in a sample of single stars. The possibility that the passive disks are caused by the presence of an as yet undetected companion at a small separation (0.3-3 AU) is possible for any individual system; however, it cannot account for the spectral type dependence of the passive disk sample as a whole. We propose that these passive disks represent a subset of T Tauri stars that are undergoing significant disk evolution. The fraction of observed passive disks and the observed spectral type dependence can both be explained by models of disk evolution that include disk photoevaporation from the central star.

Among the binaries found in young clusters, stars in different stages of disk evolution are not rare.
“Among the binaries found in young clusters, stars in different stages of disk evolution are not rare”

The Results (page unavailable) report that five of six passive-disk systems are mixed binaries, with a passive-disk star paired with a star showing different accretion properties. This supports the existence of such pairs in the surveyed star-forming regions, but the paper says the sample is small and the tendency is not statistically significant; it does not establish how common different disk-evolution stages are among young binaries generally. (LLM, conf=0.78)
Experimental — accuracy not yet measuredOf the binaries studied by Monin et al. (2007) and McCabe et al. (2006), roughly 1/100 could be like J1407 with a weak-lined T Tauri primary and a low-mass secondary with a passive disk.
“Thus, of the binaries studied by Monin et al. (2007) and McCabe et al. (2006) we can crudely estimate that 1/100 could be like J1407 with a weak-lined T Tauri primary and a low-mass secondary with a passive disk (however, this fraction should diminish as one gets to older pre-MS stars with ages of >10 7 yr).”

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.
