Bridging the gap between stars and planets
Aina Palau, Dimitris Stamatellos, Matthew Bate +58
The formation mechanisms of brown dwarfs (BDs) and free-floating planets (FFPs) are poorly constrained. The two main competing scenarios include the star-like scenario, where these…
Simultaneous evolution of the virial parameter and star formation rate in molecular clumps undergoing global hierarchical collapse
Vianey Camacho, Enrique Vázquez-Semadeni, Aina Palau +2
We compare dense clumps and cores in a numerical simulation of molecular clouds (MCs) undergoing global hierarchical collapse (GHC) to observations in two MCs at different evolutio…
Flipping-up the field: gravitational feedback as a mechanism for young clusters dispersal
Manuel Zamora-Avilés, Javier Ballesteros-Paredes, Jesús Hernández +3
Recent analyses of Gaia data have provided direct evidence that most young stellar clusters are in a state of expansion, with velocities of the order of ~0.5 km/s. Traditionally, e…
Global Hierarchical Collapse In Molecular Clouds. Towards a Comprehensive Scenario
Enrique Vázquez-Semadeni, Aina Palau, Javier Ballesteros-Paredes +2
We present a unified description of the scenario of Global Hierarchical Collapse and fragmentation (GHC) in molecular clouds (MCs), owing to the continuous decrease of the average…
Structure and Expansion Law of HII Regions in structured Molecular Clouds
Manuel Zamora-Avilés, Enrique Vázquez-Semadeni, Ricardo F. González +6
We present radiation-magnetohydrodynamic simulations aimed at studying evolutionary properties of H\,{\normalsize II} regions in turbulent, magnetised, and collapsing molecular clo…
Molecular Cloud Evolution VI. Measuring cloud ages
Enrique Vázquez-Semadeni, Manuel Zamora-Avilés, Roberto Galván-Madrid +1
In previous contributions, we have presented an analytical model describing the evolution of molecular clouds (MCs) undergoing hierarchical gravitational contraction. The cloud's e…
Are fibres in molecular cloud filaments real objects?
Manuel Zamora-Avilés, Javier Ballesteros-Paredes, Lee W. Hartmann
We analyse the morphology and kinematics of dense filamentary structures produced in a numerical simulation of a star--forming cloud of $1.4 \times 10^4 \, \Msun$ evolving under th…
Magnetized converging flows towards the hot core in the intermediate/high-mass star-forming region NGC 6334 V
Carmen Juárez, Josep M. Girart, Manuel Zamora-Avilés +7
We present Submillimeter Array (SMA) observations at 345 GHz towards the intermediate/high-mass cluster-forming region NGC 6334 V. From the dust emission we spatially resolve three…
Supernova Feedback in Molecular Clouds: Global Evolution and Dynamics
Bastian Körtgen, Daniel Seifried, Robi Banerjee +2
We use magnetohydrodynamical simulations of converging warm neutral medium flows to analyse the formation and global evolution of magnetised and turbulent molecular clouds subject…
Gravity or Turbulence? The velocity dispersion-size relation
Javier Ballesteros-Paredes, Lee W. Hartmann, Enrique Vázquez-Semadeni +2
We discuss the nature of the velocity dispersion vs. size relation for molecular clouds. In particular, we add to previous observational results showing that the velocity dispersio…
