Insights from the “Red Devil” AT 2022fpx: A Dust-reddened Family of Tidal Disruption Events Excluded by Their Apparent Red Color?

We report unnoticed but intriguing features in the peculiar nuclear transient AT 2022fpx, and investigate its type. These features include the constantly red optical color of g − r > 0, a stable soft X-ray flare ( kT ∼ 100 eV) in the past ∼550 days, a prominent mid-infrared echo peaked at ∼10 ^43.3...
