Delayed Outflows Explain Late Radio Flares in TDEs
Analysis
This paper addresses the challenge of explaining late-time radio flares observed in tidal disruption events (TDEs). It compares different outflow models (instantaneous wind, delayed wind, and delayed jet) to determine which best fits the observed radio light curves. The study's significance lies in its contribution to understanding the physical mechanisms behind TDEs and the nature of their outflows, particularly the delayed ones. The paper emphasizes the importance of multiwavelength observations to differentiate between the proposed models.
Key Takeaways
- •Delayed outflows, particularly delayed winds, are crucial for explaining late-time radio flares in TDEs.
- •The instantaneous wind model struggles to reproduce delayed radio flare events.
- •Multiwavelength observations are essential for distinguishing between different outflow mechanisms (wind vs. jet).
Reference
“The delayed wind model provides a consistent explanation for the observed radio phenomenology, successfully reproducing events both with and without delayed radio flares.”
