We compile observations of early-type binaries identified via spectroscopy, eclipses, long-
baseline interferometry, adaptive optics, common proper motion, etc. Each observational …

Abstract Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to
an understanding of its formation and evolution. However, stellar ages are difficult to obtain …

Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical
heating and phase-mixing in their disks. Such features have also been observed in our own …

Abstract We introduce the Making Galaxies In a Cosmological Context (MAGICC)
programme of smoothed particle hydrodynamics simulations. We describe a parameter …

The initial mass function (IMF), binary fraction, and distributions of binary parameters (mass
ratios, separations, and eccentricities) are indispensable inputs for simulations of stellar …

Context. As endpoints of stellar evolution, white dwarfs (WDs) are powerful tools to study the
evolutionary history of the Galaxy. In particular, the multiplicity of WDs contains information …

The growth of galaxies is one of the key problems in understanding the structure and
evolution of the universe and its constituents. Galaxies can grow their stellar mass by …

Quenching, the cessation of star formation, is one of the most significant events in the life
cycle of galaxies. While quenching is generally thought to be linked to their central regions …

We present a detailed analysis of the white dwarf luminosity functions derived from the local
40 pc sample and the deep proper motion catalog of Munn et al. Many previous studies …

We use Gaia data release 2 (DR2) magnitudes, colours, and parallaxes for stars with G< 12
to explore a parameter space with 15 dimensions that simultaneously includes the initial …
