Accretion disks around T Tauri stars
Abstract
The authors examine the proposition that many T Tauri stars are still actively accreting material from a surrounding disk of material formed at the same time as the star. It is shown that the observations are both unified and explained if classical T Tauri stars are chromospherically active pre-main-sequence stars with accretion disks. Contemporaneous optical and ultraviolet observations, along with extensive photometric monitoring in the optical and infrared, are used to test disk models and to show that there is evidence for accretion in the range 5×10-8 - 5×10-7M_sun;yr-1 from stars exhibiting strong ultraviolet excesses. These models also explain the infrared spectrum shortward of 10 μm and the total system luminosities.

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.
