Scientific paper

We present results of a VLA 3.6 cm B-configuration study of a region around the Herbig Be star LkHα 101. We detect 16 sources down to 5 sigma (rms) thresholds of 0.25 mJy. Most of the sources are thought to be young stellar objects associated with the star formation region. Six of the objects have optical counterparts, and at least two are weak-lined T Tauri stars. A large number exhibit high-amplitude variability, indicating that gyrosynchrotron emission from flares just above the photosphere is a primary cause of the emission. We discuss the distance to the star formation region as implied by the radio flux densities and Hipparcos data. We present evidence that the region may be located at a distance typical of the Taurus-Auriga star formation complex, not at the 800 pc suggested by previous studies.
