Description
Infrared photometry is reported from 1.25 to 10 micrometers for 10
Seyfert 1.8 and 1.9 galaxies identified by Osterbrock and his
collaborators and drawn originally from the Markarian lists. The three
objects whose infrared colors are the most nonstellar in nature are
objects whose ultraviolet or optical spectra preclude heavy reddening of
either the nonstellar continuum or the broad-line region. For the
remaining Seyfert 1.8 and 1.9 galaxies, the near-infrared colors are
dominated by starlight, distinctly different from the nonstellar colors
typical of Seyfert 1 galaxies. Although nonstellar 10-micrometer
emission is observed for a number of the Seyfert 1.8 and 1.9 galaxies,
in no case does it dominate the near infared luminosity, in contrast to
the Seyfert 1 galaxies where this is frequently the case.
