Description
We present High Resolution Cross Correlation Spectroscopy (HRCCS) observations and atmospheric retrieval results of the Ultra Hot Jupiter, MASCARA-1b. HRCCS is a novel technique used to characterize exoplanets with ground-based instruments by utilizing the planet's time-resolved Doppler shifted signal to separate it from the dominant stellar and telluric lines. The high spectral resolution along with wide wavelength coverage allows for robust constraints on molecular abundances and thermal structures using bayesian retrieval techniques.
We present our atmospheric retrieval results of MASCARA-1b using data taken from the IGRINS instrument (R~45000) at Gemini South. This high fidelity data provides robust constraints on molecular abundances in order to calculate C/O ratios and probe the thermal structure of the planet.
