Prolate rotation and metallicity gradient in the transforming dwarf galaxy Phoenix
Monthly Notices of the Royal Astronomical Society(2017)
摘要
Transition type dwarf galaxies are thought to be systems undergoing the process of transformation from a star-forming into a passively evolving dwarf, which makes them particularly suitable to study evolutionary processes driving the existence of different dwarf morphological types. Here we present results from a spectroscopic survey of ∼200 individual red giant branch stars in the Phoenix dwarf, ...
