Aims. We present the results of a detailed analysis of 452 ground-based, high-resolution high S/N spectroscopic measurements spread over 4.5 years for β Canis Majoris with the aim of determining the pulsational characteristics of this star, and then using them to derive seismic constraints on the stellar parameters. Methods. We determined pulsation frequencies in the Si III 4553 A line with Fourier methods. We identified the m-value of the modes by taking the photometric identifications of the…

Current limitations to asteroseismic studies are discussed, including difficulties in mode identification and in the accurate determination of global parameters of pulsating stars, and how interferometric observations may contribute to overcome these limitations are discussed.
