The primary science goal for this mission is to identify the progenitor population of the hot horizontal branch in the globular cluster M10. These stars are UV luminous stars at the end stage of evolution that started with a long period of steady hydrogen burning on the stellar main sequence of the Hertzsprung-Russell diagram. The evolution quickens with the exhaustion of hydrogen in the stellar core when the progenitor star starts to contract and enters a phase of shell hydrogen burning. The OAxFORTIS mission observations will acquire far-UV spectra to measure the temperature, mass, radius, and chemical composition of these hot stars and determine their origin.

The Principal Invetigator is Dr. McCandliss/Johns Hopkins University
