Signature of a massive rotating metal-poor star imprinted in the Phoenix stellar stream
Andrew R. Casey, Alexander P. Ji, Terese T. Hansen +13
The Phoenix stellar stream has a low intrinsic dispersion in velocity and metallicity that implies the progenitor was probably a low mass globular cluster. In this work we use Mage…
Kinematics of Antlia 2 and Crater 2 from The Southern Stellar Stream Spectroscopic Survey (S5)
Alexander P. Ji, Sergey E. Koposov, Ting S. Li +15
We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S5).…
: The destruction of a bright dwarf galaxy as revealed by the chemistry of the Indus stellar stream
T. T. Hansen, A. P. Ji, G. S. Da Costa +13
The recently discovered Indus stellar stream exhibits a diverse chemical signature compared to what is found for most other streams due to the abundances of two outlier stars, Indu…
