DESCRIPTION:Speakers: Peter Smith (Arizona State University)\nRetrievals o
 n high spectral resolution exoplanet observations have been recently made 
 possible\, allowing us now to place robust\, quantitative constraints on t
 heir atmospheres in unprecedented detail. High resolution data can also be
  combined with low resolution\, space-based data in retrievals\, probing a
  wider range of altitudes and incorporating continuum information otherwis
 e lost through detrending methods common in high resolution spectroscopy. 
 We present retrieval results of combined observations of a benchmark hot J
 upiter WASP-77A b\, combining multiple nights taken with the IGRINS instru
 ment on Gemini South (R~45\,000)\, data from WFC3 on the Hubble Space Tele
 scope (R~100)\, and IRAC/Spitzer photometry. We report a slightly superste
 llar C/O ratio and a substellar metallicity\, indicative of diverse format
 ion pathways for hot Jupiters.\n\nhttps://iaus379.aip.de/event/16/contribu
