Absence of Rapid Line Variations in Consecutive FEROS and NARVAL Spectra of Maia.
MONIER R.
Abstract (from CDS):
The comparison of four consecutive high signal-to-noise FEROS spectra of Maia, the fourth brightest member of the Pleiades open cluster, taken over 10 minutes, reveals no real line variations. The analysis of four consecutive I NARVAL profiles of Maia taken over 18 minutes does not show variations either. In particular, the five lines of He I at 4471.48 Å are constant over this timescale in both sets of data. The He I line at 3926.54 Å is very broad and diffuse compared to other photospheric lines of Maia.
