Stellar obliquity, the angle between a star's rotation and its planets' orbits, offers valuable insights into planetary system formation and evolution. Our recent research focused on the unique WASP-148 system, specifically WASP-148b, a hot Jupiter with a warm Jupiter companion. Using WIYN/NEID and Keck/HIRES spectroscopic measurements, we observed that WASP-148b aligns with its host star's spin axis. This organized configuration is common among compact multi-planet systems around cool stars. However, there are exceptions, as high-mass and hot stars often host misaligned planets. The causes for these variations remain an intriguing area for future exploration.
