Abstract
We present the Polstar SMEX mission concept, a far-ultraviolet spectropolarimeter operating in the 115-285 nm range capturing all four Stokes parameters (IQUV) at a spectral resolution of 20,000, which is equivalent to a velocity resolution of 15 km/s. Polstar investigates the astrophysical processes driven by rapid rotation and their impact on the properties, evolution, and compact object remnants of massive stars. Polstar’s projected launch would be around 2031, observing 200 or more stars to meet its scientific goals. Polstar is designed to be a generally applicable high-resolution FUV spectrometer, providing for a vigorous and scientifically diverse Guest Observer program in an extended mission phase.
