Strangelet dwarfs

If the surface tension of quark matter is low enough, quark matter is not self-bound. At sufficiently low pressure and temperature, it will take the form of a crystal of positively charged strangelets in a neutralizing background of electrons. In this case, there will exist, in addition to the usual family of strange stars, a family of low-mass large-radius objects analogous to white dwarfs, which we call strangelet dwarfs. Using a generic parametrization of the equation of state of quark matter, we calculate the massradius relationship of these objects.
