Abstract

In this paper we describe the design, science objectives, and preliminary results of the Dual-channel Extreme Ultraviolet Continuum Experiment (DEUCE). DEUCE is a dual-channel, sounding-rocket borne spectrograph consisting of a Wolter-II telescope and the largest MCP detector ever own in space. The DEUCE science objective is to obtain the first 700-1150 A spectra of highly ionizing hot stars in order to calibrate stellar models and better understand the role of such stars in ionization upkeep. DEUCE launched in December 2018 and obtained a quality spectrum of B star Epsilon Canis Majoris, which is preliminarily presented and discussed.
