Scientific paper

The far-infrared emission from some early-type galaxies with dust lanes indicates that star formation is taking place there. The ultraviolet radiation from newly formed stars heats the dust to temperatures higher than expected for H I regions illuminated by the integrated flux of the entire galaxy. Parallels with polar ring galaxies are drawn and an evolutionary scheme from dark lane to polar ring galaxy is suggested.
