| Title: | The catalogue of O-F0 stars in the southern part of Orion association |
| Authors: | Straizys V.L. |
| Abstract: |
The spectral types, magnitudes and color-indices of O-F0 stars up to 12m for the area around Great Orion Nebula are given. The magnitudes and colors were determined photographically and then reduced to the system B, V. Detaled description of the spectral classification and the determination of magnitudes is given in papers [1] and [2]. Five stars enumerated in table on page 2 are suspected in variability. |
