Pulsation-induced Spectroscopic Variability of IRAS Z02229+6208

Pulsation-induced Spectroscopic Variability of IRAS Z02229+6208

Monitoring of high-resolution spectra in the optical and near-infrared wavelength region was carried out for the early post-AGB stage star IRAS Z02229+6208 with the CARMENES instrument to reveal spectroscopic variability over the pulsation cycle of 154 days. Significant changes are seen in both the...
