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…
