a: heliocentric radial velocities for our investigated region. Blue: a single radial velocity measurement and the associated uncertainty for Hα, observed with the Southern African Large Telescope (SALT). Red: temperature vs. radial velocity for H I gas within the investigated region, observed with the Australia Telescope Compact Array (ATCA). Black: histogram of stellar radial velocities from Ramachandran et al. (2019), covering a population of ∼100 photometered stars, or ∼10% of the photometered population. b: MCELS narrow-band Hα image of the SMC Wing highlighting the supergiant shell SMC-SGS 1. Points indicate the locations of stars among the combined photometric and spectroscopic sample, with marker color representing radial velocity and marker size representing difference from the stellar median radial velocity of 170 km s−1.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
