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…
Series of core collapse numerical simulations (SOLANUM) I: Modelling the early and late infall in a sun-like protostar
D. Navarro-Almaida, B. Commerçon, U. Lebreuilly +5
Magnetohydrodynamical simulations and interferometric observations toward young stellar objects reveal the accretion of gas that may alter the physical properties and chemical comp…
Numerical Insights into Disk Accretion, Eccentricity, and Kinematics in the Class 0 phase
Adnan Ali Ahmad, Benoît Commerçon, Elliot Lynch +4
The formation and early evolution of protoplanetary disks are governed by a wide variety of physical processes during a gravitational collapse. Observations have begun probing disk…
Turn up the light: Radiative efficiency of protostars at birth
Asmita Bhandare, Adnan Ali Ahmad, Benoît Commerçon
Early stages of stellar birth comprise of a two-step process involving the formation of two hydrostatic cores. The second step of gravitational collapse sets the radiative efficien…
Brown Dwarf Formation Through Gravitational Collapse: Insights From 3D Numerical Simulations
Adnan Ali Ahmad, Benoît Commerçon, Gilles Chabrier +1
The formation mechanism of Brown Dwarfs (BDs), whether akin to stars or ejected planetary-mass objects, remains debated. We present the first 3D radiation-MHD simulations of magnet…
Birth of magnetized low-mass protostars and circumstellar disks
Adnan Ali Ahmad, Matthias González, Patrick Hennebelle +2
Although protostars and disks are often studied separately owing to numerical and observational challenges, breakthroughs in recent years have highlighted the need to study both ob…
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…
Formation of low mass protostars and their circumstellar disks
Adnan Ali Ahmad, Matthias González, Patrick Hennebelle +1
The birth process of circumstellar disks remains poorly constrained due to observational and numerical challenges. Recent numerical works have shown that the small-scale physics, o…
The birth and early evolution of a low mass protostar
Adnan Ali Ahmad, Matthias González, Patrick Hennebelle +1
Understanding the collapse of dense molecular cloud cores to stellar densities and the subsequent evolution of the protostar is of importance to model the feedback effects such an…
