Perturbations induced by a molecular cloud on the young stellar disc in the Galactic Centre

Michela Mapelli, Alessia Gualandris, Tristen Hayfield

The Galactic centre (GC) is a crowded environment: observations have revealed the presence of (molecular, atomic and ionized) gas, of a cusp of late-type stars, and of ~100 early-t…

The collapse of protoplanetary clumps formed through disc instability: 3D simulations of the pre-dissociation phase

M. Galvagni, T. Hayfield, A. C. Boley +3

We present 3D smoothed particle hydrodynamics simulations of the collapse of clumps formed through gravitational instability in the outer part of a protoplanetary disc. The initial…

In situ formation of SgrA* stars via disk fragmentation: parent cloud properties and thermodynamics

M. Mapelli, T. Hayfield, L. Mayer +1

The formation of the massive young stars surrounding SgrA* is still an open question. In this paper, we simulate the infall of a turbulent molecular cloud towards the Galactic Cent…

Clumps in the Outer Disk by Disk Instability: Why They are Initially Gas Giants and the Legacy of Disruption

Aaron C. Boley, Tristen Hayfield, Lucio Mayer +1

We explore the initial conditions for fragments in the extended regions ( AU) of gravitationally unstable disks. We combine analytic estimates for the fragmentation of…

Resolving mixing in Smoothed Particle Hydrodynamics

J. I. Read, T. Hayfield, O. Agertz

Standard formulations of smoothed particle hydrodynamics (SPH) are unable to resolve mixing at fluid boundaries. We use an error and stability analysis of the generalised SPH equat…

In situ formation of the massive stars around SgrA*

M. Mapelli, T. Hayfield, L. Mayer +1

The formation of the massive young stars surrounding SgrA* is still an open question. In this paper, we simulate the infall of an isothermal, turbulent molecular cloud towards the…
