Query: A WISE View of IRAS Debris Disks: Revising the Dust Properties   Debris disks around stars are considered as components of planetary systems.
Constrain the dust properties of these disks can give crucial information to
formation and evolution of planetary systems. As an all-sky survey,
\textit{InfRared Astronomical Satellite} (\iras) gave great contribution to the
debris disk searching which discovered the first debris disk host star (Vega).
The \iras-detected debris disk sample published by Rhee \citep{rhe07} contains
146 stars with detailed information of dust properties. While the dust
properties of 45 of them still can not be determined due to the limitations
with the \iras\ database (have \iras\ detection at 60 $\mu$m only). Therefore,
using more sensitivity data of \textit{Wide-field Infrared Survey Explorer}
(\wise), we can better characterize the sample stars: For the stars with \iras\
detection at 60 $\mu$m only, we refit the excessive flux densities and obtain
the dust temperatures and fractional luminosities; While for the remaining
stars with multi-bands \iras\ detections, the dust properties are revised which
show that the dust temperatures were over estimated in high temperatures band
before. Moreover, we identify 17 stars with excesses at the \wise\ 22 $\mu$m
which have smaller distribution of distance from Earth and higher fractional
luminosities than the other stars without mid-infrared excess emission. Among
them, 15 stars can be found in previous works.
