Title Using Beta Centauri to Probe the Wind-Photosphere Connection
DOI https://doi.org/10.5270/esa-wbwxyih
Abstract The B1 III star Beta Centauri is a Beta Cephei variable with a high X-raycount rate. In the first observation of this star with a high-resolutionX-ray spectrograph, we will determine if the X-rays are widely distributedin the wind by using the forbidden, intercombination, and resonance lines of O VII along with line profile information. The efficiency of XMM-Newton is used to full advantage in this project because at the same time the RGS spectrum is being taken, the co-pointed PN and MOS instruments will give us a light curve with extremely high statistical confidence. This light curve will be used to probe the connection between the photospheric pulsations and the X-ray production in the wind.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
