| This implies that the Milky Way grew its stellar mass mostly by in-situ star formation. | |
| The suppression of star formation activity in the central region of galaxies below the MS hints at inside-out quenching, as star formation is still ongoing in the outer regions. | |
| The star-formation efficiency is in the range 1-10% per free-fall time, consistent with the notion that the pressure balance that sets the local star-formation law in the Milky Way may well be universal out to the highest star-formation intensities. | |
| Yet when they do form, the associated star formation activity is very high, with numerous compact clusters of similar age in the same complex and evidence for a galaxy-wide perturbation as the trigger. | |
| We find that a great majority of the current star formation has occurred in gravitationally unstable regions, and that evidence of triggered star formation is prevalent at both large and local scales. | |
23 Citations | Taken at face value, the data suggest that at sufficiently early epochs, dwarf galaxy halos above the atomic cooling mass limit can be among the most efficient sites of star formation in the universe. |
| Its location in the inner Galaxy, presumably close to the end of the Galactic bar, adds to the increasing evidence for vigorous star formation in the inner regions of the Milky Way. | |
| Our results show that all the galaxies appear to have experienced their most recent star formation episode less than 107 years ago, in good agreement with previous values found in the literature. | |
| Different environmental conditions can play a crucial role in determining final products of the star formation process, and in this context, less favorable activities of star formation are expected in the external regions of our Galaxy. | |
| Consistently, the statistical analysis of positions and ages of clusters in the Milky Way disk strongly suggests that a correlation between the duration of star formation in a region and its size does exist. |

Where is star formation taking place in the Orion Nebula?5 answersStar formation in the Orion Nebula is occurring predominantly in the Orion Nebula Cluster (ONC), which is the most massive active star-forming region within a kiloparsec of the Sun. The ONC exhibits an age gradient with distance, indicating a propagation of the star-forming front into the cloud, with younger stars located closer to the center. Additionally, the ONC shows a weak signature of expansion, possibly driven by unstable N-body interactions among stars. The region contains escaping star candidates concentrated at the core, with proper motions aligned along the Orion filament, suggesting ongoing star formation processes. This detailed analysis sheds light on the dynamics and kinematics of star formation within the Orion Nebula Cluster.
