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…
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…
Precise determination of circumstellar disk lifetimes: Disk evolution in a single star-forming region
Fabian A. Polnitzky, Sebastian Ratzenböck, Josefa E. Großschedl +1
Determining how long circumstellar disks last is key to understanding the timescale of planet formation. Typically, this is done by measuring the fraction of young stars with infra…
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…
Toward the fabric of the Milky Way I. The density of disk streams from a local pc volume
Sebastian Ratzenböck, João Alves, Emily L. Hunt +3
We studied 12 disk streams found in a 250 pc volume in the solar neighborhood, which we define as coeval and comoving stellar structures with aspect ratios greater than 3:1…
