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…
Formation and evolution of a protoplanetary disk: combining observations, simulations and cosmochemical constraints
Alessandro Morbidelli, Yves Marrocchi, Adnan Ali Ahmad +12
We present a plausible and coherent view of the evolution of the protosolar disk that is consistent with the cosmochemical constraints and compatible with observations of other pro…
Protostellar Disk Formation Regimes: Angular Momentum Conservation versus Magnetic Braking
Hsi-Wei Yen, Yueh-Ning Lee
Protostellar disks around young protostars exhibit diverse properties, with their radii ranging from less than ten to several hundred au. To investigate the mechanisms shaping this…
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…
Protoplanetary disk size under non-ideal magnetohydrodynamics: A general formalism with inclined magnetic field
Yueh-Ning Lee, Barshan Ray, Pierre Marchand +1
Many mechanisms have been proposed to alleviate the magnetic catastrophe, which prevents the Keplerian disk from forming inside a collapsing magnetized core. Such propositions incl…
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…
Fragmentation with Discontinuous Galerkin schemes: Non-linear fragmentation
Maxime Lombart, Mark Hutchison, Yueh-Ning Lee
Small grains play an essential role in astrophysical processes such as chemistry, radiative transfer, gas/dust dynamics. The population of small grains is mainly maintained by the…
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…
Universal protoplanetary disk size under complete non-ideal magnetohydrodynamics: The interplay between ion-neutral friction, Hall effect, and the Ohmic dissipation
Yueh-Ning Lee, Pierre Marchand, Yu-Hsuan Liu +1
The role of non-ideal magnetohydrodynamics has been proven critical during the formation of the protoplanetary disk, particularly in regulating its size. We provide a simple model…
Tidal pull of the Earth strips the proto-Moon of its volatiles
S. Charnoz, P. A. Sossi, Y-N Lee +7
Prevailing models for the formation of the Moon invoke a giant impact between a planetary embryo and the proto-Earth \citep{Canup_2004, Cuk_Stewart_2012}. Despite similarities in t…
Protoplanetary disk formation from the collapse of a prestellar core
Yueh-Ning Lee, Sébastien Charnoz, Patrick Hennebelle
While it is generally accepted that the magnetic field and its non-ideal effects play important roles during the stellar formation, simple models of pure hydrodynamics and angular…
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…

Formation and Evolution of Disks around Young Stellar Objects
Bo Zhao, Kengo Tomida, Patrick Hennebelle +9
Recent observations have suggested that circumstellar disks may commonly form around young stellar objects. Although the formation of circumstellar disks can be a natural result of…
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…
