ALMAGAL. VIII. Early phases of triggered star formation in source AG286.0716-1.8229

Key Points

This research aims to examine the early stages of triggered star formation within a specific galactic region.
Utilized millimeter dust continuum data from the ALMAGAL survey.
Conducted high-resolution ALMA observations of selected cores.
Analyzed archival data from the SARAO Meerkat Galactic Plane Survey.
Estimated chemical composition and temperatures of observed cores.
Detected nine cores in the region with varying mass estimates between 2-16 solar masses.
Four cores identified as prestellar core candidates with properties consistent with bound objects.
Derived spectral index consistent with optically thin free-free emission.
Confirmed spatial coinciding of cores with H ii regions, indicating potential influences on star formation.
