HRCCS is a novel technique used to characterize exoplanets with ground-based ins truments by utilizing the planet's time-resolved Doppler shifted signal to separate it from the dominant stellar and telluric lines. The high spectr al resolution along with wide wavelength coverage allows for robust constr aints on molecular abundances and thermal structures using bayesian retrie val techniques. \n\n\nWe present our atmospheric retrieval results of MASC ARA-1b using data taken from the IGRINS instrument (R~45000) at Gemini Sou th. This high fidelity data provides robust constraints on molecular abund ances in order to calculate C/O ratios and probe the thermal structure of the planet.\n\nhttps://iaus379.aip.de/event/16/contributions/139/ LOCATION:Leibniz Institute for Astrophysics Potsdam (AIP) Lecture Hall URL:https://iaus379.aip.de/event/16/contributions/139/ END:VEVENT END:VCALENDAR
