A truly Newtonian softening length for disc simulations
Jean-Marc Huré, Audrey Trova
The softened point mass model is commonly used in simulations of gaseous discs including self-gravity while the value of associated length λremains, to some degree, controversial.…
Self-gravity in thin discs and edge effects: an extension of Paczynski's approximation
Audrey Trova, Jean-Marc Huré, Franck Hersant
As hydrostatic equilibrium of gaseous discs is partly governed by the gravity field, we have estimated the component caused by a vertically homogeneous disc, with a special attenti…
Exact, singularity-free recasting of the Newtonian potential in continuous media
Jean-Marc Huré
The gravitational potential is a key function involved in many astrophysical problems. Its evaluation inside continuous media from Newton's law is known to be challenging because o…
The potential of discs from a "mean Green function"
A. Trova, J. M. Huré, F. Hersant
By using various properties of the complete elliptic integrals, we have derived an alternative expression for the gravitational potential of axially symmetric bodies, which is free…
A substitute for the singular Green kernel in the Newtonian potential of celestial bodies
Jean-Marc Huré, Andreas Dieckmann
The "point mass singularity" inherent in Newton's law for gravitation represents a major difficulty in accurately determining the potential and forces inside continuous bodies. Her…
The Newtonian potential of thin disks
Jean-Marc Huré, Franck Hersant
The one-dimensional, ordinary differential equation (ODE) by Huré & Hersant (2007) that satisfies the midplane gravitational potential of truncated, flat power-law disks is extende…
