This page contains the graphs and results from the masters thesis completed by Richard D Mellinger Jr under the supervision of Dr. Fridolin Weber at San Diego State University in the Physics Department.

The Thesis, entitled QUARK-HADRON COMPOSITION OF ROTATING NEUTRON STARS, can be downloaded from the SDSU library here.

Each section has the name of the equation of state created by Drs. Milva Orsaria and Gustavo Contrera as described in M. Orsaria, H. Rodrigues, F. Weber, and G. Contrera, "Quark deconfinement in high-mass neutron stars," Phys. Rev. C89, 015806 (2014).

The differences between the equations of state are summarized in the following table, where the "section" notes the section in the thesis that contains the results for that equation of state.

The equations of states, the following plots, and much of the data used to create said plots can be downloaded as a zip file from dropbox: https://www.dropbox.com/s/uzwdgd0stw5h35r/Final_Plots.zip or found below.

For each equation of state noted above you will find the following plots:

• Particle GIF: an animated GIF showing the change in shape of the regions containing different particles as the neutron star spins down from Kepler frequency

• Phase GIF: an animated GIF showing the change in shape of the regions containing different phases of the material as the neutron star spins down from Kepler frequency

• Equatorial Particle Plot and Polar Particle Plot: plots of the maximum equatorial or polar radius one would expect to find a given particle for a given frequency

• Equation of State: a plot of the equation of state with an overlay of the second derivative (used to determine the phase boundaries) as well as the values of the boundaries

• FvsA: a figure showing the central density determined for a given baryon number and frequency, as explained in section 4.1 of the thesis

The following data files can also be found for each equation of state (after all 6 figures):

• EoS: The equation of state used. The columns are Energy Density (MeV/fm^3), Pressure (MeV/fm^3), Baryon Number Density (fm^-3)

• OmVsR: the numerical data that was used to generate the Equatorial and Polar Particle Plots.

• fvsA: the numerical data used to create the plot labeled fvsA

A guide to reading the data files can be found here

Notes:

• Not all plots/animations/data reach all the way to the Kepler frequency for the reasons explained in Section 4.2 of the thesis.

• The baryon numbers of the stars depicted in the Particle and Phase GIFs are not explicitly stated on the GIFs, but the baryon numbers used for those are the same as the values reported on the Equatorial and Polar Particle Plots.
