The goal of the DEUCE (Dual-channel Extreme Ultraviolet Continuum Spectrograph) mission is to measure the amount of the Lyman continuum (LyC) radiation that is being produced by the only two non-white-dwarf stars in our galaxy known to have a sufficiently low enough neutral hydrogen column density to measure their ionizing radiation directly. The results of this mission will help to answer one of the major questions of modern astrophysics concerning how and when galaxies first formed and how did their formation “feedback” into their circumgalactic environments to modify early galaxy formation during the Epoch of Re-ionization at Z=6-11. This mission is a re-fly of 36.311 UG.

DEUCE will observe the only two non-white-dwarf stars in our own galaxy known to have a sufficiently low neutral hydrogen column density to measure their ionizing radiation directly: Beta Canis Major (βCMa) and Epsilon Canis Major (εCMa).

The Principal Investigator is Dr. Green, University of Colorado.
