Abstract:
We present the CoRoT light curve of the bright B2.5V star HD 48977
observed during a short run of the mission in 2008, as well as a
high-resolution spectrum gathered with the HERMES spectrograph at the
Mercator telescope. We use several time series analysis tools to
explore the nature of the variations in the light curve. We performed
a detailed analysis of the spectrum of the star to determine its
fundamental parameters and its element abundances. We find a large
number of high-order g-modes, and one rotationally induced frequency.
We find stable low-amplitude frequencies in the p-mode regime as well.
Description:
HD 48977 was observed by CoRoT with a cadence of 32s during a
short run in 2008, from 2454531.48027 JD (5 May) to 2454556.76361
(31 May), i.e., during some 25 days.
