These are three research papers, all free to read on arXiv, about Euphrosyne, including two family-level papers labeled as such. We summarize each one in plain English from its abstract.
Our own artist's impression. No figures are taken from the papers.
How big Euphrosyne is, what shape it has and how it spins.
What they foundEuphrosyne is nearly spherical, ice-rich, and has a small moon.
VLT/SPHERE images and light curves, with a 3D shape model and satellite orbit fit.
How Euphrosyne moves, and the gravity and sunlight forces that shape its path.
What they foundMembers of the Euphrosyne family can drift into near-Earth orbits, and they could be a source of dark near-Earth asteroids.
Family-level context: this paper studies the Euphrosyne asteroid family, not Euphrosyne specifically.
Orbit simulations of family members from breakup to today.
Where Euphrosyne came from and how it formed and changed over time.
What they foundThe family members show similar spectra, and simulations constrain the family's collisional origin and age.
Family-level context: this paper studies the Euphrosyne asteroid family, not Euphrosyne specifically.
IRTF spectroscopy plus impact and orbit simulations.
New papers on Euphrosyne, checked weekly, summarized after a person reads it.
No new papers on Euphrosyne this week. We check arXiv every week.
We search arXiv for Euphrosyne 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.
