Query: The ODYSSEUS Survey. Motivation and First Results: Accretion, Ejection,
  and Disk Irradiation of CVSO 109   The Hubble UV Legacy Library of Young Stars as Essential Standards (ULLYSES)
Director's Discretionary Program of low-mass pre-main-sequence stars, coupled
with forthcoming data from ALMA and JWST, will provide the foundation to
revolutionize our understanding of the relationship between young stars and
their protoplanetary disks. A comprehensive evaluation of the physics of disk
evolution and planet formation requires understanding the intricate
relationships between mass accretion, mass outflow, and disk structure. Here we
describe the Outflows and Disks around Young Stars: Synergies for the
Exploration of ULLYSES Spectra (ODYSSEUS) Survey and present initial results of
the classical T Tauri Star CVSO 109 in Orion OB1b as a demonstration of the
science that will result from the survey. ODYSSEUS will analyze the ULLYSES
spectral database, ensuring a uniform and systematic approach in order to (1)
measure how the accretion flow depends on the accretion rate and magnetic
structures, (2) determine where winds and jets are launched and how mass-loss
rates compare with accretion, and (3) establish the influence of FUV radiation
on the chemistry of the warm inner regions of planet-forming disks. ODYSSEUS
will also acquire and provide contemporaneous observations at X-ray, optical,
NIR, and millimeter wavelengths to enhance the impact of the ULLYSES data. Our
goal is to provide a consistent framework to accurately measure the level and
evolution of mass accretion in protoplanetary disks, the properties and
magnitudes of inner-disk mass loss, and the influence of UV radiation fields
that determine ionization levels and drive disk chemistry.
