The simulations reconstruct the chain of events by which a stellar core, similar to the remnant of a tidally disrupted red giant star, might evolve under the gravitational tides of a massive black hole.
Most star clusters in the galactic disk dissolve rapidly, their stars migrating away from each other under the influence of gravitational tides.
A theory offered by the team to explain the puzzle is that "moonquakes"-- seismic shaking brought on by meteorite impacts or gravitational tides from Earth -- may have caused Shackleton's walls to slough off older, darker soil, revealing newer, brighter soil underneath.
Methone and S/2007 $4 probably didn't initially have the orbits that they do now but fell under the influence of Mimas as gravitational tides exerted by Saturn caused the two small bodies to drift toward the large satellite, says Murray.
The team also looked for signs that the star was stretched into a football shape by gravitational tides from the orbiting planet.
While most can be attributed to things like meteorite strikes, the Earth's gravitational tides, and day/night temperature changes, it's remotely possible that some moonquakes might be associated with ongoing scarp formation, according to Watters.
If one such star dived toward our galaxy's central black hole, radiation and gravitational tides would rip apart its disk in a matter of years.
