The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The Aa and Ab components of GLS 11 448, both classified as O3.5 II(f*), are the two most massive O stars ever detected according to the evolutionary masses of 70±10 M⊙ and 76±11 M⊙ determined in this paper.

C2weakest assumption

Evolutionary masses rest on the assumption that standard stellar evolution tracks apply without major revision to these very massive, rapidly rotating O stars; the disentangling also assumes the UNWIND algorithm can cleanly separate the spectra without residual contamination from wind or circumstellar material.

C3one line summary

M3W reports a new orbit and evolutionary masses of 70 and 76 solar masses for the O3.5 components of GLS 11 448 plus a library of 631 diffuse interstellar bands including 119 new identifications.
