A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets
O Teboul, BD Metzger - The Astrophysical Journal Letters, 2023 - iopscience.iop.org
Only a tiny fraction∼ 1% of stellar tidal disruption events (TDEs) generate powerful
relativistic jets evidenced by luminous hard X-ray and radio emissions. We propose that a …
