Abstract / Description:We present 3-160 mum photometry obtained with
the Infrared Array Camera (IRAC) and Multiband
Imaging Photometer for Spitzer (MIPS)
instruments for the first five targets from the
Spitzer Space Telescope Legacy Science Program
``Formation and Evolution of Planetary Systems''
and 4-35 mum spectrophotometry obtained with the
Infrared Spectrograph (IRS) for two sources. We
discuss in detail our observations of the debris
disks surrounding HD 105 (G0 V, 30+/-10 Myr) and
HD 150706 (G3 V, ~700+/-300 Myr). For HD 105,
possible interpretations include large bodies
clearing the dust inside of 45 AU or a reservoir
of gas capable of sculpting the dust
distribution. The disk surrounding HD 150706 also
exhibits evidence of a large inner hole in its
dust distribution. Of the four survey targets
without previously detected IR excess, spanning
ages 30 Myr to 3 Gyr, the new detection of
excess in just one system of intermediate age
suggests a variety of initial conditions or
divergent evolutionary paths for debris disk
systems orbiting solar-type stars.
