N1 - Funding Information:
This work was supported by HST AR-16129 and benefited from discussions with the ODYSSEUS team ( https://sites.bu.edu/odysseus/ ). Based on observations obtained with the NASA/ESA Hubble Space Telescope, retrieved from the Mikulski Archive for Space Telescopes (MAST) at the Space Telescope Science Institute (STScI). STScI is operated by the Association of Universities for Research in Astronomy Inc. under NASA contract NAS 5-26555. Based on observations collected at the European Southern Observatory under ESO program 106.20Z8. We acknowledge financial support from the project PRIN-INAF 2019 “Spectroscopically Tracing the Disk Dispersal Evolution (STRADE).” G.J.H. is supported by National Key R&D Program of China No. 2019YFA0405100 and by National Science Foundation of China general grant 11773002. J.H. and J.S. acknowledge support from the National Research Council of México (CONACyT) project No. 86372 and the PAPIIT-UNAM project IA102921. F.M.W. acknowledges support through NSF grant 1611443. J.C.W. and A.S.A. are supported by the STFC grant No. ST/S000399/1. Observing time with SMARTS/CHIRON is made possible by a research support grant from Stony Brook University. This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program under grant agreement Nos. 716155 (SACCRED) and 681601 (BuildingPlanS). This paper utilizes the D’Alessio irradiated accretion disk (DIAD) code. We wish to recognize the work of Paola D’Alessio, who passed away in 2013. Her legacy and pioneering work live on through her substantial contributions to the field. We thank Hodari-Sadiki James, Leonardo Paredes, and Todd Henry for managing the CHIRON spectrograph and for their prompt scheduling of the requested observations. Time on the AAVSOnet is awarded competitively; we acknowledge the contributions of AAVSO to supporting variable star science and thank Ken Menzies for coordinating and scheduling the observations. We thank the referee for a constructive review.

N2 - 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 Atacama Large Millimeter/submillimeter Array and James Webb Space Telescope, 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, near-IR, 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.
