These are four research papers, all free to read on arXiv, about Kallichore, including three family-level papers labeled as such. We summarize each one in plain English from its abstract.

How big Kallichore is, what shape it has and how it spins.
What they foundKallichore is an elongated body with an area-equivalent diameter of about 3.8 km, and its orbit uncertainty was cut by up to about 80%.
Hubble photometry, a multi-site stellar occultation and Gran Telescopio Canarias observations.
What they foundThe physical properties of the Ananke- and Carme-group moons follow log-logistic distributions.
Family-level context: this paper studies the Ananke and Carme groups (and the Pasiphae group) as statistical populations, not Kallichore specifically.
Statistical tests of more than 20 distributions.
What Kallichore is made of and how its surface behaves.
What they foundHimalia, Elara and Carme have dark surfaces like carbon-rich meteorites.
Family-level context: this paper studies three larger irregular moons of Jupiter (Himalia, Elara and Carme), not Kallichore specifically.
IRTF near-infrared spectra and spectral unmixing.
Where Kallichore came from and how it formed and changed over time.
What they foundJWST spectra show Jupiter's irregular moons have varied origins; small moons track the colours of their family's largest member.
Family-level context: this paper studies eight of Jupiter's larger irregular moons, including Carme, Ananke and Pasiphae, the namesakes of the retrograde groups, not Kallichore specifically.
JWST NIRSpec spectra of eight irregular moons.
New papers on Kallichore, checked weekly, summarized after a person reads it.
No new papers on Kallichore this week. We check arXiv every week.
We search arXiv for Kallichore 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.
