The mass of our Milky Way
Wenting Wang, Jiaxin Han, Marius Cautun +2
We perform an extensive review of the numerous studies and methods used to determine the total mass of the Milky Way. We group the various methods into seven broad classes, includi…
Inferring the velocity of early massive stars from the abundances of extremely metal-poor stars
Arthur Choplin, Nozomu Tominaga, M. N. Ishigaki
The nature of the first massive stars may be inferred by investigating the origin of the extremely metal-poor (EMP) stars, likely formed from the ejecta of one or a few previous ma…
Chemical abundances of field halo stars -- Implications for the building blocks of the Milky Way
Miho N. Ishigaki
I would like to review recent efforts of detailed chemical abundance measurements for field Milky Way halo stars. Thanks to the advent of wide-field spectroscopic surveys up to a s…
Boötes IV: A New Milky Way Satellite Discovered in the Subaru Hyper Suprime-Cam Survey and Implications for the Missing Satellite Problem
Daisuke Homma, Masashi Chiba, Yutaka Komiyama +13
We report on the discovery of a new Milky Way (MW) satellite in Boötes based on data from the on-going Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP). This satellite, named…
Evidence for the accretion origin of halo stars with an extreme r-process enhancement
Qian-Fan Xing, Gang Zhao, Wako Aoki +4
Small stellar systems like dwarf galaxies are suggested to be the main building blocks of our Galaxy by numerical simulations in Lambda CDM models. The existence of star streams li…
Evidence for an aspherical Population III supernova explosion inferred from the hyper metal-poor star HE1327-2326
Rana Ezzeddine, Anna Frebel, Ian U. Roederer +6
We present observational evidence that an aspherical supernova explosion could have occurred in the First stars in the early universe. Our results are based on the First determinat…
Evidence for the Third Stellar Population in the Milky Way's Disk
Daniela Carollo, Masashi Chiba, Miho Ishigaki +6
The Milky Way is a unique laboratory, where stellar properties can be measured and analyzed in detail. In particular, stars in the older populations encode information on the mecha…
