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:…
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…
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 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 cosmic waltz of Coma Berenices and Latyshev 2 (Group X). Membership, phase-space structure, mass, and energy distributions
J. Olivares, N. Lodieu, V. J. S. Béjar +3
Context. Open clusters (OCs) are fundamental benchmarks where theories of star formation and stellar evolution can be tested and validated. Coma Ber and Latyshev 2 (Group X) are th…
Dynamical age of the Tucana-Horologium young stellar association
Phillip A. B. Galli, Núria Miret-Roig, Hervé Bouy +2
The Tucana-Horologium association is one of the closest young stellar groups to the Sun and despite the close proximity its age is still debated in the literature. We take advantag…
The cosmic DANCe of Perseus I: Membership, phase-space structure, mass, and energy distributions
J. Olivares, H. Bouy, N. Miret-Roig +4
Context. Star-forming regions are excellent benchmarks for testing and validating theories of star formation and stellar evolution. The Perseus star-forming region being one of the…
Infrared Spectroscopy of free-floating planet candidates in Upper Scorpius and Ophiuchus
H. Bouy, M. Tamura, D. Barrado +15
Context: A rich population of low-mass brown dwarfs and isolated planetary mass objects has been reported recently in the Upper Scorpius and Ophiuchus star forming complex. Aims: W…
The lithium-rotation connection in the newly discovered young stellar stream Psc-Eri (Meingast 1)
J. Arancibia-Silva, J. Bouvier, A. Bayo +4
Context. As a fragile element, lithium is a sensitive probe of physical processes occurring in stellar interiors. Aims. We aim at investigating the relationship between lithium abu…
Structure and kinematics of the Taurus star-forming region from Gaia-DR2 and VLBI astrometry
P. A. B. Galli, L. Loinard, H. Bouy +9
Aims:We take advantage of the second data release of the Gaia space mission and the state-of-the-art astrometry delivered from very long baseline interferometry observations to rev…
The seven sisters DANCe IV. Bayesian hierarchical model
J. Olivares, L. M. Sarro, E. Moraux +8
Aims. We develop, test and characterise of a new statistical tool (intelligent system) for the sifting and analysis of nearby young open cluster (NYOC) populations. Methods. Using…
