Nucleosynthesis in neutron-rich ejecta from quark-novae
Prashanth Jaikumar, Bradley S. Meyer, Kaori Otsuki +1
We explore heavy-element nucleosynthesis by rapid neutron capture (r-process) in the decompressing ejecta from the surface of a neutron star. The decompression is triggered by a vi…
Temperature Effects on Core g-modes of Neutron Stars
Nicholas Lozano, Vinh Tran, Prashanth Jaikumar
Neutron stars provide a unique physical laboratory to study the properties of matter at high density. We study a diagnostic of the composition of high-density matter, namely, g-mod…
Spindown of Isolated Neutron Stars: Gravitational Waves or Magnetic Braking?
Jan Staff, Prashanth Jaikumar, Vincent Chan +1
We study the spindown of isolated neutron stars from initially rapid rotation rates, driven by two factors: (i) gravitational wave emission due to r-modes and (ii) magnetic braking…
-mode oscillations of dark matter admixed neutron stars
Swarnim Shirke, Debarati Chatterjee, Prashanth Jaikumar
We investigate -mode oscillations in dark matter admixed neutron stars employing a relativistic mean field model to describe hadronic matter and a model for self-interacting fer…
Muon production in low-energy electron-nucleon and electron-nucleus scattering
Prashanth Jaikumar, Daniel R. Phillips, Lucas Platter +1
Recently, muon production in electron-proton scattering has been suggested as a possible candidate reaction for the identification of lepton-flavor violation due to physics beyond…
Skyrmion Stars: Astrophysical motivations and implications
Prashanth Jaikumar, Rachid Ouyed
We study mass-radius relations for compact stars employing an equation of state (EOS) of dense matter based on a Skyrme fluid. The zero-temperature mean-field model is based on mes…
