Aims. The blue compact dwarf galaxy IIZw71 is catalogued as a probable polar-ring galaxy, and along its long axis it has several very luminous knots showing recent episodes of star formation. Our main aim is to study the physical properties, the stellar content, and the kinematics in the brightest knots of the polar ring Methods. We carried out long-slit… (More)
Table 3. Relative observed and reddening corrected line intensities [F(Hβ)=I(Hβ)=1000] for the different observed knots of IIZw71. For each knot we also give the flux of Hβ, once reddening corrected and after subtraction of the underlying absorption and the constant of reddening, with their corresponding errors.
