Why coronal mass ejections are necessary for the dynamo
Axel Brandenburg
Large scale dynamo-generated fields are a combination of interlocked poloidal and toroidal fields. Such fields possess magnetic helicity that needs to be regenerated and destroyed…
Impact of nuclear "pasta" on neutrino transport in collapsing stellar cores
Hidetaka Sonoda, Gentaro Watanabe, Katsuhiko Sato +3
Nuclear ``pasta'', nonspherical nuclei in dense matter, is predicted to occur in collapsing supernova cores. We show how pasta phases affect the neutrino transport cross section vi…
RApid Temporal Survey - RATS II: Followup observations of 4 newly discovered short period variables
Gavin Ramsay, Ralf Napiwotzki, Pasi Hakala +1
The RApid Temporal Survey (RATS) is a survey to detect objects whose optical intensity varies on timescales of less than ~70 min. In our pilot dataset taken with the INT and the Wi…
Can the thermal instability drive turbulence?
Axel Brandenburg, Maarit J. Korpi, Antony J. Mee
The thermal instability with a piecewise power law cooling function is investigated using one- and three-dimensional simulations with periodic and shearing-periodic boundary condit…
Primordial Stellar Feedback and the Origin of Hyper Metal-Poor Stars
Torgny Karlsson
The apparent absence of stars in the Milky Way halo with -5 ~< [Fe/H] ~< -4 suggests that the gas out of which the halo stars were born experienced a period of low or delayed star…
Turbulence from localized random expansion waves
Antony J. Mee, Axel Brandenburg
In an attempt to determine the outer scale of turbulence driven by localized sources, such as supernova explosions in the interstellar medium, we consider a forcing function given…
