Using the Advanced Camera for Surveys aboard the Hubble Space Telescope , we have discovered dust-scattered light from the debris disk surrounding the F2V star HD 15745 .
The circumstellar disk is detected between 2.0 \arcsec and 7.5 \arcsec radius , corresponding to 128 - 480 AU radius .
The circumstellar disk morphology is asymmetric about the star , resembling a fan , and consistent with forward scattering grains in an optically thin disk with an inclination of \sim 67 \arcdeg to our line of sight .
The spectral energy distribution and scattered light morphology can be approximated with a model disk composed of silicate grains between 60 and 450 AU radius , with a total dust mass of 10 ^ { -7 } ~ { } M _ { \odot } ( 0.03 M _ { \earth } ) representing a narrow grain size distribution ( 1 - 10 \mu m ) .
Galactic space motions are similar to the Castor Moving Group with an age of \sim 10 ^ { 8 } yr , although future work is required to determine the age of HD 15745 using other indicators .
