Cooling of a rotating strange star with a crust
As a strange star spins down, the nuclear matter in its crust contracts continuously into the quark core. The confined nuclear matter is dissolved into quark matter, liberating a lot of thermal energy. This process is called deconfinement heating. It is found that deconfinement heating dramatically changes the thermal evolution of a strange star. For a strange star with a strong surface magneti...
متن کاملHow large can the crust of a strange star be?
The effect of the magnetic field on the electrostatic potential of electrons inside and in close vicinity outside the quark surface of the star is studied. Depending on the value of the crust potential and the electron chemical potential at the base of the nuclear crust, we find that the strong surface magnetic field, 1.0 × 1014 ≤ H ≤ 3.0 × 1016 Gauss leads to a considerable reduction of the el...
متن کاملSeismic signatures of strange stars with crust
We study acoustic oscillations (eigenfrequencies, velocity distributions, damping times) of normal crusts of strange stars. These oscillations are very specific because of huge density jump at the interface between the normal crust and the strange matter core. The oscillation problem is shown to be self-similar. For a low (but non-zero) multipolarity l the fundamental mode (without radial nodes...
متن کاملThe crust of rotating strange quark stars
Calculations of the properties of rotating strange stars with crusts are performed within the framework of general relativity. We employ an equation of state (EOS) of strange quark matter based on the MIT Bag Model with massive strange quarks and lowest order QCD interactions. The crust is described by the BPS equation of state. A significant increase of the stellar radius is found close to the...
متن کاملDurability of Neutron Star Crust
How long do neutron star mountains last? The durability of elastically deformed crust is important for neutron star physics including pulsar glitches, emission of gravitational waves from static mountains, and flares from star quakes. The durability is defined by the strength properties of the Yukawa crystals of ions, which make up the crust. In this paper we extend our previous results [Mon. N...
