  • Anomalous Silicate Dust Emission in the Type 1 Liner Nucleus of M81 

    Li, Aigen; Li, M. P.; Kohler, M. (American Astronomical Society, 2010)
    We report the detection and successful modeling of the unusual 9.7μm Si-O stretching silicate emission feature in the type 1 (i.e., face-on) LINER nucleus of M81. Using the Infrared Spectrograph (IRS) instrument on Spitzer, ...

  • Complex Organic Materials in the HR 4796A Disk? 

    Kohler, M.; Mann, I.; Li, Aigen (Institute of Physics, 2008)
    The red spectral shape of the visible to near-infrared reflectance spectrum of the sharply edged ringlike disk around the young main-sequence star HR 4796A was recently interpreted as the presence of tholin-like complex ...
