Abstract

All stars with masses less than roughly 10 Msun will end their lives as white dwarfs:
Earth-sized, burnt-out stellar embers sustained by electron
degeneracy. The steep slope of the stellar initial mass function
implies that the overwhelming majority of all stars born in the Galaxy
will evolve, or already have evolved, into white dwarfs. The study of
these stellar remnants links into a wide range of astrophysical
problems, such as stellar mass loss, the galactic star formation
history, the late evolution of planetary systems, or supernova type Ia
progenitors. I will provide an overview of the recent progress in
these research areas, predominantly driven by SDSS, and I will outline
the impact that future instruments such as GAIA, 4MOST, WEAVE, or LSST
will have.
