Exact shering box solutions of MHD flows with resistivity, viscosity and cooling
P. Lesaffre, S. A. Balbus
Axisymmetric incompressible modes of the magneto-rotational instability (MRI) with a vertical wavenumber are exact solutions of the non-linear local equations of motion for a disk…
Effects of turbulent diffusion on the chemistry of diffuse clouds
P. Lesaffre, M. Gerin, P. Hennebelle
Aims. We probe the effect of turbulent diffusion on the chemistry at the interface between a cold neutral medium (CNM) cloudlet and the warm neutral medium (WNM). Methods. We perfo…
Cosmological Implications of the Second Parameter of Type Ia Supernovae
Philipp Podsiadlowski, Paolo A. Mazzali, Pierre Lesaffre +2
Theoretical models predict that the initial metallicity of the progenitor of a Type Ia supernova (SN Ia) affects the peak of the supernova light curve. This can cause a deviation f…
The dynamical influence of cooling in the envelope of prestellar and protostellar cores
P. Lesaffre, A. Belloche, J. -P. Chieze +1
We compute numerical simulations of spherical collapse triggered by a slow increase in external pressure. We compare isothermal models to models including cooling with a simple but…
The Double Pulsar J0737--3039: Testing the Neutron Star Equation of State
Ph. Podsiadlowski, J. D. M. Dewi, P. Lesaffre +3
The double pulsar J0737--3039 has become an important astrophysical laboratory for testing fundamental physics. Here we demonstrate that the low measured mass of Pulsar B can be us…
A two-stream formalism for the convective Urca process
P. Lesaffre, Ph. Podsiadlowski, C. A. Tout
We derive a new formalism for convective motions involving two radial flows. This formalism provides a framework for convective models that guarantees consistency for the chemistry…
