Accelerated gas flow along Ophiuchus B44 filament: Breaking Position-Position-Velocity degeneracy

J. Alves, C. Zucker, C. Lada +15

(Abridged) Stellar feedback from massive stars in the Upper-Sco has been proposed to have reshaped the gas in the nearby Ophiuchus complex. In this framework, feedback organizes th…

The velocity field of the Scorpius-Centaurus OB association

S. Hutschenreuter, J. Alves, L. Posch +5

We present a non-parametric reconstruction of the three-dimensional velocity field of the Scorpius-Centaurus OB association (Sco- Cen). Using Gaia DR3 astrometry and radial velocit…

Direct measurement of ISM proper motion with image registration

M. Piecka, L. Posch, S. Meingast +3

To date, quantification of the on-sky motion for interstellar clouds have relied on proxies such as young stellar objects (YSO) and masers. We present the first direct measurement…

The TW Hydrae Association is a cluster chain of Sco-Cen

N. Miret-Roig, J. Alves, S. Ratzenböck +9

The TW Hydrae Association (TWA) is a young local association (YLA) about 50 pc from the Sun, offering a unique opportunity to study star and planet formation processes in detail. W…

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…
