TL;DR: In this paper, the authors simulate the evolution of low-metallicity halo stars at distances up to 3 kpc using the binary population synthesis code SeBa and compare the results with the observed halo WDLF of white dwarfs in the SuperCOSMOS Sky Survey.

TL;DR: In this paper, the authors simulate the evolution of low-metallicity halo stars at distances up to 3 kpc using the binary population synthesis code SeBa and use two different white dwarf cooling models to predict the present-day luminosities of halo white dwarfs.

TL;DR: In this article, the Munich-Groningen semi-analytical model of galaxy formation with the high resolution Aquarius simulations of dark matter haloes was used to study the assembly history of the stellar spheroids of six Milky Way-mass galaxies, focussing on building block properties such as mass, age and metallicity.

TL;DR: In this paper, the authors investigate the effect of the kick velocities that neutron star binaries receive upon their formation, in the building block galaxies (BBs) that partly formed the stellar halo by merging with our Galaxy.

TL;DR: In this paper, a semi-analytic model for galaxy formation is applied to the high-resolution Aquarius dark matter simulations, and the authors investigate if the properties of these building blocks are reflected in the halo white dwarf (WD) population in the Solar neighborhood.
