Scientific paper

We report the first detection of Lyman continuum (approximately 600A) emission from a non-degenerate star. The Wide Field Camera (WFC) on-board ROSAT detected emission from beta CMa (B1 II-III) which has a very low interstellar column. Both Kurucz local thermodynamic equilibrium (LTE)line-blanketed and Mihalas non-local thermodynamic equilibrium (NLTE) un-blanketed model atmospheres can match the observed count rate within the very considerable absolute calibration errors. We also find very marginal evidence for variability, although not at the dominant period of the known optical pulsations.
