Re-visiting the Canis Major star-forming region with Gaia data release 3 data
S. Nogueira-Silva, P. A. B. Galli, J. Olivares +7
Context: The Canis Major (CMa) star-forming region, a remote molecular cloud complex within the recently discovered Radcliffe Wave, remains under-explored in the literature. Aims:…
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 internal kinematics of local young stellar associations. Identifying correlations among age, expansion, rotation, and shear
J. Olivares, N. Miret-Roig, P. A. B. Galli
Context. The local (<200 pc away) young (<50 Myr old) stellar associations (LYSA) provide fundamental evidence for the study of the star formation process in the local neighbourhoo…
Disk fraction among free-floating planetary-mass objects in Upper Scorpius
Tommy Rodrigues, Hervé Bouy, Sean N. Raymond +9
Free-floating planetary-mass objects (FFPs) have been detected through direct imaging in several young, nearby star-forming regions. The properties of circumstellar disks around th…
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…
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…
