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…
The evolution of velocity dispersion in the Sco-Cen OB association
Josefa E. Großschedl, João Alves, Sebastian Ratzenböck +4
We study how the stellar velocity dispersion within the Scorpius-Centaurus OB association (Sco-Cen) has evolved over approximately 20 million years, from its formation to the prese…
Most nearby young star clusters formed in three massive complexes
Cameren Swiggum, João Alves, Robert Benjamin +9
Efforts to unveil the structure of the local interstellar medium and its recent star formation history have spanned the past seventy years. Recent studies utilizing precise data fr…
The Corona Australis star formation complex is accelerating away from the Galactic plane
L. Posch, N. Miret-Roig, J. Alves +5
We study the kinematics of the recently discovered Corona Australis (CrA) chain of clusters by examining the 3D space motion of its young stars using Gaia DR3 and APOGEE-2 data. Wh…
