【 摘 要 】

Exploiting a stiff equation of state of the relativistic mean-field model MKVORH ϕwithσ -scaled hadron effective masses and couplings, including hyperons, we demonstrate that the existing neutron-star cooling data can be appropriately described within “the nuclear medium cooling scenario” under the assumption that different sources have different masses.
