Overview

Population study reveals fragmentation patterns in dense cores, suggesting turbulence influences star formation.

Key Points

  • This study aims to analyze the characteristics and fragmentation of dense cores in the Serpens/Aquila star-forming region.
  • Conducted observations with Atacama Large Millimeter/submillimeter Array (ALMA) at 106 GHz
  • Analyzed 100 gravitationally unstable dense cores and their fragmentation into starless and protostellar structures
  • Implemented synthetic observations from turbulent magnetohydrodynamical simulations to predict starless core detections.
  • Identified 66 continuum sources with 2 completely starless and 9 within protostellar cores
  • Predictions from simulations align with the observed detection of 1.19 starless cores
  • Observed an increase in multiplicity at smaller scales corresponding to higher fragmentation in larger structures.
