摘要：

We describe near-IR imaging data for a sample of 23 Class I sources in the Taurus-Auriga dark clouds. Combining our data with previous photometry, we detect brightness variations of similar to0.1-0.5 mag in many sources. The near-IR morphologies are consistent with millimeter continuum measurements. Most (similar to60%) of the sample are true protostars; the rest may be objects in transition between Class I and Class II, T Tauri stars with edge-on disks, or heavily reddened T Tauri stars.
