Study of the photosphere of β Monocerotis A
Spectrograms of β Mon A were obtained at CTIO with the 1.5 m reflector in 10 Å/mm and 20 Å/mm. From this analysis of the He I liens we obtained a velocity curve with P=3.56 h and K=20 km/s. In phases with positive acceleration an emission was observed superimposed in the absorption profile of Mg II...

| Sumario: | Spectrograms of β Mon A were obtained at CTIO with the 1.5 m reflector in 10 Å/mm and 20 Å/mm. From this analysis of the He I liens we obtained a velocity curve with P=3.56 h and K=20 km/s. In phases with positive acceleration an emission was observed superimposed in the absorption profile of Mg II λ 4481 Å. |
