Abstract
Spectra of five condensations in the Herbig-Haro object HH 448 are presented for the first time. The emission line intensities indicate a low degree of ionization, 3–5%, with an electron density of 103–104 cm−3. The relative intensities of the emission lines of the individual condensations show that their physical properties differ. We classify the two stars closest to HH 448 as main sequence dwarfs which are, most likely, not coupled to HH 448. The absorption in the region of HH 448 is at least 4m.3.
