DESCRIPTION:Speakers: Hayley Beltz (University of Michigan)\nUltrahot Jupi
 ters are ideal candidates to explore with high-resolution emission spectra
 . Detailed theoretical studies are necessary to investigate the range of s
 pectra we can expect to see from these objects throughout their orbit\, be
 cause of the extreme temperature and chemical longitudinal gradients that 
 exist across day and nightside regions. Using previously published 3D GCM 
 models of WASP-76b with different treatments of magnetic drag\, we post-pr
 ocess the 3D atmospheres to generate high-resolution emission spectra for 
 two wavelength ranges and throughout the planet's orbit. We find that the 
 high-resolution emission spectra vary strongly as a function of phase\, at
  times showing emission features\, absorption features\, or both\, which a
 re a direct result of the 3D structure of the planet. At phases exhibiting
  both emission and absorption features\, the Doppler shift differs in dire
 ction between the two spectral features\, making them differentiable inste
 ad of canceling each other out. Through the use of cross-correlation\, we 
 find different patterns in net Doppler shift for models with different tre
 atments of drag: the nightside spectra show opposite signs in their Dopple
 r shift\, while the dayside phases have a reversal in the trend of net shi
 ft with phase.\n\nhttps://meetings.aip.de/event/16/contributions/132/
