Optical-infrared photometry of the "isolated" T Tauri star V4046 Sgr.

Optical and infrared photometry - including intermediate-band photometry in the 8-13 micron window - of the isolated T Tauri star V 4046 Sgr is presented. The optical photometry is consistent with a K 5 V classification, negligible reddening and distance 42 pc. There is no evidence of a near infrared excess but there is clear evidence for emission by silicate grains at a temperature of about 200 K. There is a possibility that the 10-micron and 20-micron fluxes are variable.
