Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?
I. Mendigutía, N. Huélamo, I. Jiménez-Serra +32
The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…
Disc fragmentation. I. Ejection of Jupiter-mass Free Floating Planets from growing binary systems
Aleksandra Ćalović, Sergei Nayakshin, Sarah Casewell +1
Over the past 25 years, observations have uncovered a large population of free-floating planets (FFPs), whose origins remain debated. Massive FFPs (several Jupiter masses or more)…
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…
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…
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…
Bayesian ages of local young stellar associations I. Through the expansion rate method
J. Olivares, N. Miret-Roig, P. A. B. Galli +1
Context. Local young stellar associations (LYSAs <50 Myr and <150 pc) are important laboratories to test predictions from star-formation theories. Estimating their ages through var…
Multiplicity of young isolated planetary mass objects in Taurus and Upper Scorpius
H. Bouy, G. Duchêne, G. Strampelli +12
Free-floating planetary mass objects--worlds that roam interstellar space untethered to a parent star--challenge conventional notions of planetary formation and migration, but also…
The Solar System's passage through the Radcliffe wave during the middle Miocene
E. Maconi, J. Alves, C. Swiggum +14
Context. As the Solar System orbits the Milky Way, it encounters various Galactic environments, including dense regions of the interstellar medium (ISM). These encounters can compr…
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…
