The second flight of DEUCE obtained a fantastic spectrum of the hot B star Epsilon Canis Majoris.
Upon publication of the results, the full flight spectrum will be made available here as a text file.
The DEUCE EUV exposure, the first-ever flux-calibrated exposure of a hot ionizing star from 730-900A. Lots of scattered light, showing the difficulty of the measurement, but none that impinges on the science spectrum.
The DEUCE FUV exposure, from 911 to 1144A.
These images represent the first ever flux-calibrated spectrum of an ionizing hot star from 730-1150A, and will help test stellar models at these regimes and help better understand the potential role of B stars in ionization and modern ionization upkeep.
A placeholder spectrum, showing the data-gap for Epsilon CMa that the DEUCE flux-calibrated spectrum will fill. The resultant spectra are currently being analyzed, and the results will be published as soon as possible. Please stay tuned!
