Testing massive star evolution, star-formation history and feedback at low metallicity : Spectroscopic analysis of OB stars in the SMC Wing

Understand

Stars which start their lives with spectral types O and early-B are the progenitors of core-collapse supernovae, long gamma-ray bursts, neutron stars, and black holes.

• These massive stars are the primary sources of stellar feedback in star-forming galaxies.
• At low metallicities, the properties of massive stars and their evolution are not yet fully explored.
• Here we report a spectroscopic study of 320 OB stars in the Small Magellanic Cloud.
