A study by a team of scientists at the University of Sheffield suggests that stars being ripped apart due to galactic collisions might be 100 times more common than previously thought.

Yeah, it certainly makes sense there would be more tidal disruption events when galaxies are colliding!

BTW, I think this sentence needs rewriting.... (Sorry, the curse of an editor.)


The appearance of such an event had been detected during a repeat spectroscopic observations of a sample of 15 galaxies over a period of just 10 years suggested that the rate at which TDEs happen was far higher than previously thought and by a factor of 100 no less.

It appears that this would involve stars that are already deep in the core. It still looks like only a tiny fraction of all the stars in the galaxy.

100 times more than how many?
