Abstract

Dust the thing New observations of the Sun-like star HIP 8920 suggest that we are getting a glimpse of a rare and transient event. HIP 8920 is surrounded by a cloud of warm dust 100,000 times greater in mass that the ‘zodiacal dust’ found in the asteroid belt of our Solar System. This could be the product of frequent or huge collisions between asteroids or other planetesimals whose orbits are being perturbed by a nearby planet.
