Spectral energy distributions of T Tauri stars - Disk flaring and limits on accretion
Abstract
The authors analyze spectral energy distributions of T Tauri stars (TTS) to place limits on disk accretion in this early phase of stellar evolution. The results reinforce the conclusion of Adams, Lada, and Shu that much of the infrared excess emission arises from reprocessing of stellar radiation by a dusty circumstellar disk. Observational constraints on disk geometries and disk masses are derived. The relative importance of accretion and solar-type chromospheric activity in T Tauri stars is assessed. The present analysis indicates that disk accretion in the T Tauri phase does not modify stellar evolution significantly and that the angular momentum of accreted material can be lost in a stellar wind.

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.
