a b s t r a c t The ab initio quasirelativistic Hartree–Fock method developed specifically for the calculation of spectral parameters of heavy atoms and highly charged ions is used to derive transition data for a multicharged tungsten ion. The configuration interaction method is applied to include electron correlation effects. The relativistic effects are taken into account in the Breit–Pauli approximation for quasirelativistic Hartree–Fock radial orbitals. The energy level spectra, radiative lifetimes and Lande gfactors are calculated for the 4p 6 4d 2 , 4p 6 4d4f, and 4p 5 4d 3 configurations of the ion W 36+ . The transition wavelengths, spontaneous transition probabilities, oscillator strengths, and line strengths for the electric dipole, electric quadrupole, electric octupole, and magnetic dipole transitions among the levels of these configurations are tabulated.read more

Mind the Gap: The Location of the Lower Edge of the Pair-instability Supernova Black Hole Mass Gap
Robert Farmer,Mathieu Renzo,S. E. de Mink,S. E. de Mink,Pablo Marchant,Stephen Justham,Stephen Justham +6 more
TL;DR: In this article, the location of the lower edge of the mass gap at 45 M is remarkably robust against variations in the metallicity, the treatment of internal mixing, and stellar wind mass loss, making it the most robust predictor for the final stages of the evolution of massive stars.

r -process nucleosynthesis from matter ejected in binary neutron star mergers
Luke Bovard,Dirk Martin,Federico Guercilena,Almudena Arcones,Luciano Rezzolla,Luciano Rezzolla,Oleg Korobkin +6 more
TL;DR: In this paper, the authors performed full general-relativistic simulations of binary neutron-star mergers employing three different nuclear-physics equations of state (EOSs), considering both equal-and unequal-mass configurations, and adopting a leakage scheme to account for neutrino radiative losses.

The theory of atomic structure and spectra
TL;DR: In this article, the Slater-Condon theory of atomic structure and spectra is combined with a coherent set of closed-form equations suitable both for computer calculations on cases of arbitrary complexity and for hand calculations for very simple cases.
