    Ongoing star formation at the outskirts of Sextans A: spectroscopic detection of early O-type stars
    With both nebular- and stellar-derived abundances of ≲1/10 Z_{⊙ } and low foreground extinction, Sextans A is a prime candidate to replace the Small Magellanic...

    Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
    Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II)...
