Characterizing the velocity anisotropy of the Milky Way's stellar halo
F. O. Barbosa, A. Pérez-Villegas, S. Rossi +6
Modeling the Milky Way stellar halo requires well-determined density and velocity anisotropy profiles. However, it has been challenging to gather a large sample of stars with six-d…
Dynamical evolution and dissolution timescale of young stellar clusters in the Orion star-forming complex
Sergio Sánchez-Sanjuán, Ãngeles Pérez-Villegas, Jesús Hernández +1
We present a comprehensive analysis of the Orion star-forming complex (OSFC), combining structural, kinematic, and dynamical information to constrain the present-day state and futu…
Dynamical heating of newborn stars driven by accretion-induced orbital tightening
Vianey Camacho, Andrea Bonilla-Barroso, Javier Ballesteros-Paredes +2
In previous works, we have shown that stars in the Orion and the Lagoon Nebula Clusters, and simulations of collapsing clouds, exhibit constant velocity dispersion as a function of…
Kinematic study of the Orion Complex: Analysing the young stellar clusters from big and small structures
Sergio Sánchez-Sanjuán, Jesús Hernández, Ãngeles Pérez-Villegas +4
In this work, we analysed young stellar clusters with spatial and kinematic coherence in the Orion star-forming complex. For this study, we selected a sample of pre-main sequence c…
