Stellar Populations of the Outer Milky-Way Halo

Proceedings of the International Astronomical Union, 2017
AbstractThe stellar spheroidal components of the Milky-Way contain the oldest and most metal poor of its stars. Inevitably the processes governing the early stages of Galaxy evolution are imprinted upon them. According to the currently favoured hierarchical bottom-up scenario of galaxy formation, these components, specially the Galactic halo, are the ...

Stellar Substructure in the Halos of the Milky Way and M31

Proceedings of the International Astronomical Union, 2017
AbstractDedicated wide-field surveys have uncovered a variety of debris features and stellar streams in the halos of the Milky Way and M31. I briefly compare these perspectives and discuss how observations of the peripheral regions of M31 can help shape our current understanding of the Milky Way.

Stellar Archaeology in the Milky Way Halo: Variable Stars and Stellar Populations in the New Milky Way Satellites Discovered by the SDSS

AIP Conference Proceedings, 2009
We present results of a project devoted to the extensive survey of the ultra‐faint Milky Way dwarf spheroidal satellites recently discovered by the SDSS (Bootes I, Ursa Major II, Coma, Hercules, Canes Venatici I, Canes Venatici II, Leo IV), that we are monitoring for variability using time‐series multiband observations collected at a variety of ...

Elemental abundances in the Milky Way stellar disk(s), bulge, and halo

New Astronomy Reviews, 2013
We present a review of elemental abundances in the Milky Way stellar disk, bulge, and halo with a focus on data derived from high-resolution stellar spectra. These data are fundamental in disentangling the formation history and subsequent evolution of the Milky Way.

Chemical abundances of the Milky Way thick disk and stellar halo

AIP Conference Proceedings, 2012
We report the chemical abundances of 97 metal-poor stars likely belonging to the Milky Way thick disk and inner/outer stellar halo. All of the spectra of the sample stars have been obtained with the High Dispersion Spectrograph (HDS) mounted on the Subaru Telescope and have analyzed in a homogeneous manner. We show that the thick disk stars show higher
