The Oph region revisited with Gaia EDR3
Natalie Grasser, Sebastian Ratzenböck, João Alves +10
Context. Young and embedded stellar populations are important probes of the star formation process. Paradoxically, we have a better census of nearby embedded young populations than…
Evidence for Radial Expansion at the Core of the Orion Complex with Gaia EDR3
Cameren Swiggum, Elena D'Onghia, João Alves +6
We present a phase-space study of two stellar groups located at the core of the Orion complex: Briceño-1 and Orion Belt Population-near (OBP-near). We identify the groups with the…
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…
3D dynamics of the Orion cloud complex -- Discovery of coherent radial gas motions at the 100-pc scale
Josefa E. Großschedl, João Alves, Stefan Meingast +1
We present the first study of the 3D dynamics of the gas in the entire southern Orion cloud complex. We used the parallaxes and proper motions of YSOs from Gaia DR2 as a proxy for…
Extended stellar systems in the solar neighborhood. IV. Meingast 1: the most massive stellar stream in the solar neighborhood
S. Ratzenböck, S. Meingast, J. Alves +2
Nearby stellar streams carry unique information on the dynamical evolution and disruption of stellar systems in the Galaxy, the mass distribution in the disk, and provide unique ta…
A Galactic-scale gas wave in the Solar Neighborhood
João Alves, Catherine Zucker, Alyssa A. Goodman +6
For the past 150 years, the prevailing view of the local Interstellar Medium (ISM) was based on a peculiarity known as the Gould's Belt, an expanding ring of young stars, gas, and…
