[HTML][HTML] Stellar population of the Rosette Nebula and NGC 2244-Application of the probabilistic random forest

K Mužić, V Almendros-Abad, H Bouy, K Kubiak… - Astronomy & …, 2022 - aanda.org
Context. Measurements of internal dynamics of young clusters and star-forming regions are
crucial to fully understand the process of their formation. A basic prerequisite for this is a well …

Why most molecular clouds are gravitationally dominated

L Ramírez-Galeano… - Monthly Notices of …, 2022 - academic.oup.com
Observational and theoretical evidence suggests that a substantial population of molecular
clouds (MCs) appear to be unbound, dominated by turbulent motions. However, these …

Gravity or turbulence?–VI. The physics behind the Kennicutt–Schmidt relation

J Ballesteros-Paredes, M Zamora-Avilés… - Monthly Notices of …, 2024 - academic.oup.com
We explain the large variety of star formation laws in terms of one single, simple law that can
be inferred from the definition of the star formation rate and basic algebra. The resulting …

Collapsing molecular clouds with tracer particles–II. Collapse histories

DC Collins, DK Le… - Monthly Notices of the …, 2024 - academic.oup.com
In order to develop a complete theory of star formation, one essentially needs to know two
things: what collapses and how long it takes. This is the second paper in a series, where we …

Quantifying kinematic substructure in star-forming regions with statistical tests of spatial autocorrelation

B Arnold, NJ Wright, RJ Parker - Monthly Notices of the Royal …, 2022 - academic.oup.com
We investigate whether spatial-kinematic substructure in young star-forming regions can be
quantified using Moran's I statistic. Its presence in young star clusters would provide an …

Decaying turbulence in molecular clouds: how does it affect filament networks and star formation?

J Dhandha, Z Faes, RJ Smith - Monthly Notices of the Royal …, 2024 - academic.oup.com
The fragmentation of gas to form stars in molecular clouds is intrinsically linked to the
turbulence within them. These internal motions are set at the birth of the cloud and may vary …

Gravity or turbulence? VII. The Schmidt-Kennicutt law, the star formation efficiency, and the mass density of clusters from gravitational collapse rather than turbulent …

M Zamora-Aviles, V Camacho… - arXiv preprint arXiv …, 2024 - arxiv.org
We explore the Schmidt-Kennicutt (SK) relations and the star formation efficiency per free-
fall time ($\eff $), mirroring observational studies, in numerical simulations of filamentary …

Unveiling two expanding stellar groups formed through violent relaxation in the lagoon nebula cluster

A Bonilla-Barroso, J Ballesteros-Paredes… - Monthly Notices of …, 2024 - academic.oup.com
The current kinematic state of young stellar clusters can give clues on their actual dynamical
state and origin. In this contribution, we use Gaia DR3 data of the Lagoon Nebula Cluster …

Dynamics of Star Cluster Formation: Mergers in Gas-rich Environments

J Karam, A Sills - The Astrophysical Journal, 2024 - iopscience.iop.org
We perform high-resolution simulations of forming star clusters as they merge inside giant
molecular clouds (GMCs) using hydrodynamics coupled to N-body dynamics to …

The GT and GHC models for molecular clouds compared. Differences, similarities, and myths

E Vázquez-Semadeni, A Palau, GC Gómez… - arXiv preprint arXiv …, 2024 - arxiv.org
We provide a detailed comparison between the``gravoturbulent''(GT) and``global
hierarchical collapse''(GHC) models for molecular clouds and star formation, their respective …
