Description

Since the discovery of 51 Pegasi b, over 550 hot Jupiters (HJs) have been confirmed. These discoveries were made by a wide variety of ground-based and space-based surveys using many different, independent, analysis techniques. While this has been useful for confirming the validity of the discovered HJs, it has produced a sample that is plagued by unquantifiable selection biases, differing assumptions, and a lack of self-consistency. To address these issues, we aim to discover and characterize all remaining detectable HJs orbiting bright (G < 12.5 mag) FGK stars using TESS and homogeneous analysis techniques. This large-scale, collaborative, discovery effort will be combined with smaller-scale characterizations of benchmark systems that show signs of youth, planetary engulfment, and other features associated with dynamical instability. Armed with a complete, self-consistent, magnitude-limited sample of HJs and several critical benchmark systems, we will be able to comprehensively address the question of how HJs form and evolve. I will present the detailed characterization of the first dozen discoveries from the MEEP survey, and provide an early glimpse into the current population of hot Jupiters from TESS.
