Title: (Ultra)Hot Jupiters, Magnetic Effects, and the Need for 3D Atmospheric Models

Abstract: High resolution spectroscopy (R~100,000) has opened the door to planetary atmospheric characterization at an unprecedented level. With this increase in resolution, more sophisticated models, specifically those in 3D, are necessary to utilize these spectra to their fullest potential. In this talk, I discuss my work on 3D atmospheric modeling of hot and Ultrahot Jupiters and how these planets are especially amenable to 3D modeling. I will specifically focus on our 3D model's unique implementation of magnetic drag and how it impacts the resulting atmospheric structure of Ultrahot Jupiters. Additionally, I will discuss how observables--namely phase curves and high resolution spectra---are influenced by 3D effects and our magnetic drag.
