Stellar velocity distributions in binary-rich ultrafaint dwarf galaxies
Amery Gration, David D. Hendriks, Payel Das +2
Ultrafaint dwarf (UFD) galaxies are dominated by dark matter, the distribution of which may be inferred from the kinematics of that galaxy's stellar population. Star-by-star observ…
