Quark-Novae, cosmic reionization, and early r-process element production
R. Ouyed, R. E. Pudritz, P. Jaikumar
We examine the case for Quark-Novae (QNe) as possible sources for the reionization and early metal enrichment of the universe. Quark-Novae are predicted to arise from the explosive…
Quark Stars: Features and Findings
Prashanth Jaikumar
Under extreme conditions of temperature and/or density, quarks and gluons are expected to undergo a deconfinement phase transition. While this is an ephemeral phenomenon at the ult…
Quark Matter in Neutron Stars: An apercu
Prashanth Jaikumar, Sanjay Reddy, Andrew W. Steiner
The existence of deconfined quark matter in the superdense interior of neutron stars is a key question that has drawn considerable attention over the past few decades. Quark matter…
Quark deconfinement in neutron star cores: The effects of spin-down
Jan Staff, Rachid Ouyed, Prashanth Jaikumar
We study the role of spin-down in driving quark deconfinement in the high density core of isolated neutron stars. Assuming spin-down to be solely due to magnetic braking, we obtain…
Distinguishing Bare Quark Stars from Neutron Stars
Prashanth Jaikumar, Charles Gale, Dany Page +1
Observations to date cannot distinguish neutron stars from self-bound bare quark stars on the basis of their gross physical properties such as their masses and radii alone. However…
Neutrino Emission and Mass Ejection in Quark Novae
Petteri Keranen, Rachid Ouyed, Prashanth Jaikumar
We explore the role of neutrinos in a Quark Nova explosion. We study production of neutrinos during this event, their propagation and their interactions with the surrounding quark…
