A Star’s Destruction Launched a Fast Wind Before Peak Light
The first pre-peak ultraviolet spectrum of a tidal disruption event showed gas moving near 10,000 km/s.
Summary
The first pre-peak ultraviolet spectrum of a tidal disruption event showed gas moving near 10,000 km/s.
Hubble observations of TDE2025aarm about 20 days before optical maximum found broad ultraviolet absorption lines blueshifted by roughly 10,000 kilometers per second. The team interprets the spectrum and a non-blackbody continuum as evidence for an early outflow reprocessing the event's light. It is the first reported pre-peak ultraviolet spectrum of a tidal disruption event; the interpretation still comes from one nearby event.
