Classification of Finite Rings of Order p6 by Generators and Relations

open access: yesJournal of Mathematics, 2013
For any finite abelian group (R,+), we define a binary operation or “multiplication” on R and give necessary and sufficient conditions on this multiplication for R to extend to a ring. Then we show when two rings made on the same group are isomorphic. In

The Rings of (2060) Chiron: Evidence of an Evolving System

open access: yesThe Astrophysical Journal Letters
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stellar occultation observed on 2023 September 10 UT that reveals new and ...
