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

We identify four new roAp stars: TIC 312111544, TIC 252881095, TIC 46054683, and 49 Cam (TIC 393276640).

C2weakest assumption

The classification of stars as roAp based on the presence of high-frequency signals in the DFT after pre-whitening assumes that these signals are indeed pulsations and not artifacts or other types of variability.

C3one line summary

An algorithm applied to TESS data identifies four new rapidly oscillating Ap stars from LAMOST-classified Ap stars and known candidates.
