<< As (eight stars skirt a black hole 1m times the mass of the Sun) approach, all are stretched and deformed by the black hole's gravity. Some are completely pulled apart into a long stream of gas, a cataclysmic phenomenon called a tidal disruption event. Others are only partially disrupted, retaining some of their mass and returning to their normal shapes after their horrific encounters. >>
<< These simulations, (..) are the first to combine the physical effects of Einstein's general theory of relativity with realistic stellar density models. The virtual stars range from about one-tenth to 10 times the Sun's mass. >>
<< The division between stars that fully disrupt and those that endure isn't simply related to mass. Instead, survival depends more on the star's density. >>

<< This paper introduces a series of papers presenting a quantitative theory for the tidal disruption of main-sequence stars by supermassive black holes (the pericenter-dependence of tidal disruption properties for eight stellar masses (..) and six black hole masses (..). >>
