Supernova feedback in porous photoionized Giant Molecular Clouds

Cheryl S. C. Lau, Ian A. Bonnell, Yueh-Ning Lee +1

We present a new suite of numerical simulations of Type II supernovae (SNe) detonating in Giant Molecular Clouds with a variety of density structures shaped by photoionization feed…

Cosmic Threads: Interlinking the Stellar Initial Mass Function from Star-Birth to Galaxies

Tereza Jerabkova, Donatella Romano, Pavel Kroupa +19

The stellar initial mass function (sIMF) describes the distribution of stellar masses formed in a single star formation event in a molecular cloud clump. It is fundamental to astro…

The impact of shear on the rotation of Galactic plane molecular clouds

Raffaele Rani, Jia-Lun Li, Toby J. T. Moore +4

Stars form in the densest regions of molecular clouds, however, there is no universal understanding of the factors that regulate cloud dynamics and their influence on the gas-to-st…

Effective equation of state of a radiatively cooling gas: Self-similar solution of spherical collapse

Yueh-Ning Lee

The temperature of the interstellar medium (ISM) is governed by several physical process, among which radiative cooling, external UV/cosmic ray heating, and the mechanical work by…

Identification of molecular clouds in emission maps: a comparison between methods in the \ce{^{13}CO}/\ce{C^{18}O} () Heterodyne Inner Milky Way Plane Survey

Raffaele Rani, Toby J. T. Moore, David J. Eden +3

The growing range of automated algorithms for the identification of molecular clouds and clumps in large observational datasets has prompted the need for the direct comparison of t…

From Bubbles and Filaments to Cores and Disks: Gas Gathering and Growth of Structure Leading to the Formation of Stellar Systems

Jaime E. Pineda, Doris Arzoumanian, Philippe André +8

The study of the development of structures on multiple scales in the cold interstellar medium has experienced rapid expansion in the past decade, on both the observational and the…

Influence of protostellar jets and HII regions on the formation and evolution of stellar clusters

Antoine Verliat, Patrick Hennebelle, Marta González +2

Context. Understanding the conditions in which stars and stellar clusters form is of great importance. In particular the role that stellar feedback may have is still hampered by la…

What is the role of stellar radiative feedback in setting the stellar mass spectrum?

Patrick Hennebelle, Benoit Commercon, Yueh-Ning Lee +1

In spite of decades of theoretical efforts, the physical origin of the stellar initial mass function (IMF) is still debated. Particularly crucial is the question of what sets the p…

The Origin of the Stellar Mass Distribution and Multiplicity

Yueh-Ning Lee, Stella S. R. Offner, Patrick Hennebelle +5

In this chapter, we review some historical understanding and recent advances on the Initial Mass Function (IMF) and the Core Mass Function (CMF), both in terms of observations and…

What determines the formation and characteristics of protoplanetary discs?

Patrick Hennebelle, Benoît Commerçon, Yueh-Ning Lee +1

Planets form in protoplanetary discs. Their masses, distribution, and orbits sensitively depend on the structure of the protoplanetary discs. However, what sets the initial structu…

How first hydrostatic cores, tidal forces and gravo-turbulent fluctuations set the characteristic mass of stars

Patrick Hennebelle, Yueh-Ning Lee, Gilles Chabrier

The stellar initial mass function (IMF) is playing a critical role in the history of our universe. We propose a theory that is based solely on local processes, namely the dust opac…

Stellar mass spectrum within massive collapsing clumps III. Effects of temperature and magnetic field

Yueh-Ning Lee, Patrick Hennebelle

The stellar mass spectrum is an important property of the stellar cluster and a fundamental quantity to understand our Universe. The fragmentation of diffuse molecular cloud into s…

Stellar mass spectrum within massive collapsing clumps II. Thermodynamics and tidal forces of the first Larson core

Yueh-Ning Lee, Patrick Hennebelle

We investigate the dependence of the peak of the IMF on the physics of the so-called first Larson core, which corresponds to the point where the dust becomes opaque to its own radi…

Stellar mass spectrum within massive collapsing clumps I. Influence of the initial conditions

Yueh-Ning Lee, Patrick Hennebelle

We conduct numerical experiments in which we systematically vary the initial density over four orders of magnitude and the turbulent velocity over a factor ten. In a companion pape…

Analytical core mass function (CMF) from filaments: Under which circumstances can filament fragmentation reproduce the CMF?

Yueh-Ning Lee, Patrick Hennebelle, Gilles Chabrier

Observations suggest that star formation in filamentary molecular clouds occurs in a two-step process, with the formation of filaments preceding that of prestellar cores and stars.…

Formation of proto-cluster: a virialized structure from gravo-turbulent collapse I. Simulation of cluster formation in collapsing molecular cloud

Yueh-Ning Lee, Patrick Hennebelle

Stars are often observed to form in clusters. It is therefore important to understand how such a region of concentrated mass is assembled out of the diffuse medium and its properti…
