LS220Lwl (with Lambdas, with low densities)
Abstract
This EoS is an extension of the EoS by Lattimer and Swesty [LSNP_1991], including the Λ-hyperon as additional particle [GROMP_2013,OFNP_2012]. The hyperon-nucleon interaction is taken from the model by Balberg and Gal [BGNP_1997]. Photons and electrons/positrons are included as a free gas. The low density extension, below the validity range of the original Lattimer and Swesty EoS is based on a nuclear statistical equilibrium model, see Ref. [OFNP_2012]. Further details can be found in Refs. [GROMP_2013,GROP_2012,OFNP_2012]. A first application in the supernova context is described in Ref. [PONP_2013].
