The star formation history of Orion is structured and episodic

Alena Rottensteiner, João Alves, Stefan Meingast +6

The propagation of star formation throughout a molecular cloud complex can tell us much about its physical drivers and the importance of environmental versus intrinsic processes. W…

The dispersal law of young star clusters: free expansion -- A Gaia/eROSITA census of Orion and Sco--Cen

João Alves, Stefan Meingast, Alena Rottensteiner

We measure how young star clusters disperse over time in the two nearest star-forming complexes. Our sample comprises 44 \texttt{SigMA}-\textit{Gaia}-defined clusters in Orion and…

The Nearby Star Formation and Supernova Histories Reconstructed from Young Star Clusters

Cameren Swiggum, Catherine Zucker, Michelangelo Pantaleoni González +8

We reconstruct the recent star formation and core-collapse supernova (ccSN) histories of the Solar Neighborhood from the past trajectories of young star clusters. Using a \textit{G…

A comprehensive cluster census of Orion. An application of the Significance Mode Analysis (SigMA) algorithm

Alena Rottensteiner, Sebastian Ratzenböck, João Alves +2

Precise astrometric surveys and modern clustering algorithms are working in step to transform our view of star-forming regions. By revealing a much richer substructure than previou…

Kinematics of young stellar objects in NGC 2024 based on infrared proper motions

Alena Rottensteiner, Monika G. Petr-Gotzens, Stefan Meingast +6

The most recently formed young stellar objects (YSOs) in active star forming regions are excellent tracers of their parent cloud motion. Their positions and dynamics provide insigh…

An empirical isochrone archive for nearby open clusters

Alena Rottensteiner, Stefan Meingast

The ages of star clusters and co-moving stellar groups contain essential information about the Milky Way. Their special properties make them excellent tracers of galactic structure…

VISIONS: The VISTA Star Formation Atlas -- II. The data processing pipeline

Stefan Meingast, Hervé Bouy, Verena Fürnkranz +3

The VISIONS public survey provides large-scale, multiepoch imaging of five nearby star-forming regions at subarcsecond resolution in the near-infrared. All data collected within th…

VISIONS: The VISTA Star Formation Atlas -- I. Survey overview

Stefan Meingast, João Alves, Hervé Bouy +37

VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Aus…

The star formation history of the Sco-Cen association. Coherent star formation patterns in space and time

Sebastian Ratzenböck, Josefa E. Großschedl, João Alves +13

We reconstruct the star formation history of the Sco-Cen OB association using a novel high-resolution age map of the region. We develop an approach to produce robust ages for Sco-C…

Extended stellar systems in the solar neighborhood -- V. Discovery of coronae of nearby star clusters

Stefan Meingast, João Alves, Alena Rottensteiner

In this paper, we present a novel view on the morphology and the dynamical state of 10 prominent, nearby ( 500 pc), and young (30-300 Myr) open star clusters with Gaia…
