A spectroscopic study of three FU Orionis objects: Accretion disks and wind signatures

It has been suggested that in outburst, FU Ori objects (FUors) are luminous accretion disks surrounding young, low luminosity stars. We obtained high resolution, high signal-to-noise, 3985-4920 A, 4940-6830 A, and 8030-9510 A spectra of V1057 Cyg, Z CMa, and FU Ori at the Mayall telescope at KPNO to...
