01

Size, shape & spin

1 paper

How big Euphrosyne is, what shape it has and how it spins.

[1]2020astro-ph.EPPeer-reviewed

Binary asteroid (31) Euphrosyne: Ice-rich and nearly spherical

B. Yang, J. Hanus, B. Carry & 38 others

What they foundEuphrosyne is nearly spherical, ice-rich, and has a small moon.

Why it mattersIt is one of the largest main-belt asteroids, and its shape and density tell us what it is made of.
What they studied

VLT/SPHERE images and light curves, with a 3D shape model and satellite orbit fit.

02

Orbit & dynamics

1 paper

How Euphrosyne moves, and the gravity and sunlight forces that shape its path.

[2]2015astro-ph.EPPreprintFamily-level

The Euphrosyne family's contribution to the low albedo near-Earth asteroids

Joseph R. Masiero, V. Carruba, A. Mainzer & 2 others

What they foundMembers of the Euphrosyne family can drift into near-Earth orbits, and they could be a source of dark near-Earth asteroids.

Why it mattersIt links a distant asteroid family to objects that come near Earth.

Family-level context: this paper studies the Euphrosyne asteroid family, not Euphrosyne specifically.

What they studied

Orbit simulations of family members from breakup to today.

03

Origins & history

1 paper

Where Euphrosyne came from and how it formed and changed over time.

[3]2020astro-ph.EPPeer-reviewedFamily-level

Physical and dynamical characterization of the Euphrosyne asteroid Family

B. Yang, J. Hanus, M. Broz & 5 others

What they foundThe family members show similar spectra, and simulations constrain the family's collisional origin and age.

Why it mattersEuphrosyne's parent body may have been one of the bodies that delivered water and organics to the inner planets.

Family-level context: this paper studies the Euphrosyne asteroid family, not Euphrosyne specifically.

What they studied

IRTF spectroscopy plus impact and orbit simulations.

How we choose papers

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.

Our own words, our own drawings

Summaries are written by us from each paper’s abstract, not copied. Diagrams are our own simplified drawings, not figures from the papers.

Preprint vs. peer-reviewed

“Peer-reviewed” means arXiv lists a journal reference for the paper. Everything else is marked “Preprint”: shared openly, possibly before or without journal review.
