r-process nucleosynthesis in supernovae
It is expected that the discovery would lead tothe better understanding of explosive phenomena in the universe byembedding the present result into macroscopic simulations. By studying the neutrino oscillations in the realistic supernova models, we try to put the severe constraint on the unknown neutrino parameters. We show that the massive amounts of dust and the peculier extinction curves in high-z quasars can be naturally explained if a large fraction of the interstellar medium is in dense molecular-cloud phases, where efficient grain growth and coagulation occur.
In addition, the simulation achieved a computational speed of 24. Pmfamplitude and the power spectral index,and discuss prospects for better determining these quantities in the near future. Pflops on a gravitational tree-code to simulate the milky way galaxy with 18600 gpus byjeroen bédorf, evghenii gaburov, michiko s.
In turbulent molecular clouds, stars and star clusters form along the filamentary structures. In this theoretical model, a long-standing underproduction problem of the isotopic abundances above and below the typical r-process peaks around a 130, 165 and 195 is resolved, still satisfying the universal r-process abundance pattern between the early generations of metal-deficient stars and the solar-system. Direct observation of the magnetic reconnection site in a planetary magnetotail magnetic reconnection is an important plasma process in space and astrophyiscal plasmas. Wedemonstrated that the combustion will occur in the so-calledendothermic regime and there are different characteristics of themixed state of hm and qm and the appearance of strange quarks.Seeing Gravitational Sound Waves: Transients in the Local Universe (Speaker: Mansi Kasliwal) | MIT Kavli Institute for Astrophysics and Space Research
Seeing the electromagnetic (EM) counterpart would be a litmus test for whether these mergers are indeed the long sought site of r-process nucleosynthesis (and produce half the elements heavier than iron). However, the challenge is unambiguously identifying the predicted faint ... ·

Lectures will cover topics in computational relativistic astrophysics, gamma-ray bursts, r-process nucleosynthesis, nucleonic and hadronic EoSs, constraints from EM observations, and GW physics. A general conference will also be organized during the workshop. ... Neutron stars ... ·
As for the causes of the asymmetry, stellar rotation has been considered to be most promising. Observations of thermal dust emissions with herschel satellitehave revealed that molecular clouds consist ofmany filaments. This may explain the reason why the perpendicular configuration is often found between the interstellar magnetic field and the filaments.
In this article, equilibrium solutions of isothermal clouds areobtained with a self-consistent field method. Michiko fujii and simon portegies zwart, monthly notices of the royal astronomical society, 449, 726-740 neutrino scattering provides a unique signal for understanding the weak interaction processes in an extremely high-temperature and high-density matter inside the proto-neutron stars born in core-collapse supernova explosions.
