Query: Asteroid Polarimetric-Phase Behavior in the Near-Infrared: S- and
  C-Complex Objects   We present the first results of our survey of asteroid polarization-phase
curves in the near-infrared J and H bands using the WIRC+Pol instrument on the
Palomar 200-inch telescope. We confirm through observations of standard stars
that WIRC+Pol can reach the 0.1% precision needed for asteroid phase curve
characterization, and show that C-complex asteroids could act as an alternate
calibration source as they show less wavelength variation than stellar
polarized standards. Initial polarization-phase curve results for S-complex
asteroids show a shift in behavior as a function of wavelength from visible to
near-infrared bands, extending previously observed trends. Full near-infrared
polarization-phase curve characterization of individual asteroids will provide
a unique constraint on surface composition of these objects by probing the
wavelength dependence of albedo and index of refraction of the surface
material.
