On the Detection of Supermassive Primordial Stars
arXiv:1811.08911 · doi:10.3847/2041-8213/aaf80d
Abstract
The collapse of supermassive primordial stars in hot, atomically-cooled halos may have given birth to the first quasars at 15 - 20. Recent numerical simulations of these rapidly accreting stars reveal that they are cool, red hypergiants shrouded by dense envelopes of pristine atomically-cooled gas at 6,000 - 8,000 K, with luminosities 10 L. Could such luminous but cool objects be detected as the first stage of quasar formation in future near infrared (NIR) surveys? We have now calculated the spectra of supermassive primordial stars in their birth envelopes with the Cloudy code. We find that some of these stars will be visible to JWST at 20 and that with modest gravitational lensing Euclid and WFIRST could detect them out to 10 - 12. Rather than obscuring the star, its accretion envelope enhances its visibility in the NIR today by reprocessing its short-wavelength flux into photons that are just redward of the Lyman limit in the rest frame of the star.
