Abstract

We present high resolution near infrared images of the young triple system HV Tau which clearly reveal a circumstellar disk around HV Tau C. The disk is seen nearly edge-on ([FORMULA]), and has a radius of [FORMULA]. HV Tau AB, a 74 mas binary (Simon et al. 1996), is resolved as well. If HV Tau C is bound to HV Tau AB, these are the first near-IR images of a circumtertiary disk in a young multiple system.

Key words: accretion, accretion disks – stars: binaries: close – stars: circumstellar matter – stars: formation – stars: individual: HV Tau – stars: pre-main sequence

* Based on observations made at Canada-France-Hawaii Telescope
