Unmasking The Mysteries Of High-Mass X-Ray Binaries (Hmxbs): The Role Of The Electron Beam Ion Trap (Ebit), Carey L. Baxter, Greg Brown, Natalie Hell

Carey L Baxter

The Electron Beam Ion Trap (EBIT) uses a very narrow electron beam (~60μm) to excite and trap ions. X-ray emissions of the excited ions are then diffracted and analyzed. I studied specific spectral emission lines of ionized silicon. This data can be used as a point of reference for similar spectra measured by the satellite Chandra so that the Doppler shift due to wind around the accretion disks of High Mass X-ray Binaries (HMXBs) can be calculated. HMXBs are pairs of stars that are luminous in X-rays. They are composed of a donor star that gives up mass to an …
