Struve, Otto Abstract The P Cygni star HD 169226 = MWC 293 shows radial velocities ranging from - 143 km/sec for H to - 50 km/sec for Mg ii. The emission lines of H give + 89 km/sec, and the emission lines of Hei give + 141 km/sec. The star HD 217050 = MWC 394 has a peculiarly poor spectrum on the violet side of X 3647, with only Ni ii very strong. The other lines, Fe ii, Till, Cr u, etc., must be suppressed by continuous H absorption within the shell. The color of HD 160529 = MWC 266 has been found to be similar to that of a late F or early K star. The spectral type is A4sea. Pleione has shown, in July, 1943, an increase in intensity of Sc u and Fe i, which now definitely es- tablishes the evolution of its sheittoward lower ionization. AG Pegasi showed, in the summer of 1943, P Cygni absorption lines of increased strength, while Z Andromedae had stronger emission lines of Fe i than in the preceding fall and winter Publication: The Astrophysical Journal Pub Date: March 1944 DOI: 10.1086/144608 Bibcode: 1944ApJ....99..205S full text sources ADS | Related Materials (7) Part 1: 1953PASP...65..185S Part 2: 1953PASP...65...81S Part 3: 1951PASP...63..138S Part 5: 1952PASP...64...20S Part 6: 1952PASP...64..117S Part 7: 1952PASP...64..180S Part 8: 1952PASP...64..288S
