  • Close Encounters of the Stellar Kind - mpia. de
    The closest encounters with the Sun in space and time The open circles show the expected perihelion distance vs the expected perihelion time for each star The error bars mark the 5% and 95% quantiles of the distributions for each star, which together form a 90% confidence interval on the estimate
  • orbit - What are the odds that the Sun hits another star . . .
    Estimated time for stars (including the Sun) to undergo a close encounter with another star in local stellar neighborhoods Whenever two stars (or stellar remnants) pass close to each other, their planets' orbits can be disrupted, potentially ejecting them from the system entirely
  • Close encounters of the stellar kind - arXiv. org
    to identify stellar encounters and to examine their association with specific geological signatures The goal of the present work is to identify stars which have passed – or which will pass – close to the Sun How close a star must come before it has an influence depends on the star’s prop-erties
  • Close Stellar Encounters: Investigating the Distribution of . . .
    Close stellar encounters play a critical role in shaping planetary systems by perturb-ing the orbits of minor body populations like the Oort Cloud and the orbits of planets Using data from the Gaia DR3catalogue, this work quantifies close stellar encounters, investigating both Sun-star and star-star interactions
  • Close encounters of the stellar kind | Astronomy . . .
    It is important to realize that a search for close encounters preferentially includes stars with large radial velocities, anomalous or not: all other data being equal, the larger the radial velocity, the smaller the perihelion distance (as the velocity vector then points closer to the Sun)
  • Close encounters of the stellar kind - ResearchGate
    First, we examine the probability of experiencing flybys or encounters: More than 50% of stars with planet-forming discs in a typical star-forming environment should experience a close
  • Close encounters
    Having found the parameters of the close encounters, they do a back-of-the-envelope calculation of the effect it may have had on the Oort cloud Answer: very small, as you'd expect for such a low mass star travelling at high speed They say this is the closest known stellar encounter to the Sun
