Almost nothing has been published about Fornjot on its own, so this page uses four family-level papers, all free to read on arXiv, about the group it belongs to. Each one is clearly labeled “Family-level”.
Our own artist's impression. No figures are taken from the papers.
What Fornjot is made of and how its surface behaves.
What they foundNew colours for 21 irregular moons of Saturn match other irregular populations and show no ultra-red objects.
Family-level context: this paper studies the colours of 21 of Saturn's irregular moons, not Fornjot specifically.
Stacked DECam observations.
How Fornjot moves, and the gravity and sunlight forces that shape its path.
What they found64 new irregular moons were found, bringing Saturn's total to 122; small retrograde moons point to a recent collisional break-up.
Family-level context: this paper studies Saturn's irregular moons as a population, including the Norse and Inuit groups, not Fornjot specifically.
Canada-France-Hawaii Telescope images from 2019–2021.
What they foundA new dynamical study of Saturn's irregular moons separates original features from later evolution.
Family-level context: this paper studies Saturn's irregular moons as a population, not Fornjot specifically.
N-body simulations with frequency analysis.
Where Fornjot came from and how it formed and changed over time.
What they foundCentaur 2013 VZ70 may be debris from Saturn's irregular moon population.
Family-level context: this paper studies Saturn's irregular moon population, not Fornjot specifically.
N-body simulations of the centaur's orbit compared with Saturn's moons.
New papers on Fornjot, checked weekly, summarized after a person reads it.
No new papers on Fornjot this week. We check arXiv every week.
We search arXiv for Fornjot papers and keep the ones that add something new, are clearly written up and are relevant to a general reader. A person reads every abstract.
Summaries are written by us from each paper’s abstract, not copied. Diagrams are our own simplified drawings, not figures from the papers.
“Peer-reviewed” means arXiv lists a journal reference for the paper. Everything else is marked “Preprint”: shared openly, possibly before or without journal review.
