Variability study of the high-resolution spectra of an O-star - Preliminary results

Guilherme D. C. Teixeira

Massive O-stars are some of the most enigmatic astronomical stellar objects. Their masses have significant impact in the overall physics of their atmospheres.We have performed a study of the variability in the spectra of an O-star using high-resolution spectroscopic observations.I will present some of our preliminary findings and discuss some of their implications on our understanding of the physical processes driving these stars.
