The STACC 1998 Campaign on Praesepe: The Spectroscopy
Published online by Cambridge University Press: 12 April 2016
Abstract
The STACC campaign of 1998 on BN Cnc was an extensive international photometric campaign aimed at obtaining accurate frequencies of the pulsations in this star. To facilitate identification of the modes, parallel spectroscopic observations were made from six observatories around the world. I here present preliminary results from the spectroscopy made from the Nordic Optical Telescope. The accurate frequencies from the photometric campaign are used to obtain accurate amplitudes of the equivalent width variations. These results are to be used in an attempt to identify the pulsation modes in this star.
