Abstract: |
We have acquired about 1200 hr of both spectroscopic and photometric measurements of the β Cep star v Eri with 22 telescopes around the world, detecting and identifying seven independent pulsation modes. They are the radial fundamental mode, an l = 1, g1 triplet, an l = 1, p1 doublet and an l = 1, p2 singlet. Seismic model calculations by two independent teams suggest that it is not possible to explain the pulsational behavior of v Eri with standard stellar models. Some modifications of the input physics are required. |
