Rydgren, A. E. ; Vrba, F. J. Abstract UBVRI and JHK photometry is presented for 49 late-F to early-K stars in the direction of the Orion Ic association for which Smith, Beckers, and Barden (1983) have measured projected rotational velocities. Four of these stars possess T Tauri-like infrared excesses, presumably due to thermal emission from circumstellar dust. Six other stars show evidence of possible intracluster reddening. The authors find no obvious correlation between stellar luminosity and projected rotational velocity within this sample. Specifically, the slower rotators are not systematically less luminous (smaller inferred mass) than the faster rotators. The available evidence also indicates no physical connection between the gaseous circumstellar disks noted by Smith, Beckers, and Barden around the faster rotators and the presence of T Tauri-like infrared excesses.
