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

Comparing the typical separation and mass of the cores with those expected in the case of the collect and collapse scenario and with the thermal Jean length and mass, the best agreement is found with the characteristic scales in the case of triggered star formation.

C2weakest assumption

The assumption that the adopted temperature ranges (derived from chemical tracers and dust continuum) accurately represent the cores and that the observed arch alignment is causally due to the H II region rather than projection or chance alignment.

C3one line summary

ALMA data on nine cores along an arch in AG286.0716−1.8229 support triggered star formation induced by an expanding H II region.
