  1. 9. Direct formation of millisecond pulsars from rotationally delayed accretion-induced collapse of massive white dwarfs
    Dr Paulo Freire (MPI Bonn)
    24/03/2014, 14:30
    Millisecond pulsars (MSPs) are believed to be old neutron stars, formed via type~Ib/c core-collapse supernovae, which have subsequently been spun up to high rotation rates via accretion from a companion star in a highly circularised low-mass X-ray binary. The recent discoveries of Galactic field binary MSPs in eccentric orbits, and mass functions compatible with that expected for helium white...

  2. 86. Formation of Neutron Stars from the ONeMg Core of Super-AGB Stars

    The stellar mass range (8 - 10) Msun corresponds to the most massive AGB stars and the most numerous massive stars. We study the transition from super-AGB star to massive star and find that a propagating neon-oxygen burning shell is common to both the most massive electron capture supernova (EC-SN) progenitors and the lowest mass iron-core collapse supernova (FeCCSN) progenitors. Of the...

  3. 13. Ultra-stripped Type Ic supernovae from close binary evolution
    Dr Thomas Tauris (MPIfR Bonn)
    24/03/2014, 15:10
    Recent discoveries of weak and fast optical transients raise the question of their origin. We investigate the minimum ejecta mass associated with core-collapse supernovae (SNe) of Type Ic. We show that mass transfer from a helium star to a compact companion can produce an ultra-stripped core which undergoes iron core collapse and leads to an extremely fast and faint SN Ic. In this Letter, a...

  4. 33. Spectral signatures of super-luminous supernovae powered by magnetars and black holes
    Dr Jason Dexter (UC Berkeley)
    24/03/2014, 15:30
    Wide-field optical surveys have discovered a population of super-luminous supernova explosions in the past several years, including some where it is difficult to explain the light curve shape using energy deposition from radioactive decay. Many of these events can be explained by a model in which a rapidly rotating magnetar forms in the explosion and deposits its spindown energy into the...

  5. 122. Neutrino-driven wind from the aftermath of binary neutron star mergers
    Dr Albino Perego (TU Darmstadt, Institut für Kernphysik Theoriezentrum)
    24/03/2014, 15:50
    Binary neutron star mergers are among the most extreme events happening in the Universe. These very powerful events are expected to release large amounts of energy in form of neutrinos, gravitational waves and electromagnetic radiation, together with the ejection of a small fraction of their original mass. In particular, they are expected to be sites for r-process nucleosynthesis, as well...
