Camacho, I., García, M., Urbaneja, M. A., Herrero, A. 2017. B-supergiants in IC1613: testing low-Z massive star physics and evolution. Lives and Death Throes of Massive Stars, 329th Symposium of the International-Astronomical-Union (IAU) 12, 389-389, DOI: 10.1017/S1743921317002472

The physical processes taking place in massive stars during their life and death are highly dependent on the metallicity (Z) of their parent cloud. Observations of these stars in low-Z nearby galaxies are crucial to understand these processes. IC1613 is the nearest Local Group galaxy with ongoing star formation and O-abundance lower than the SMC, although UV spectroscopy suggests it is not so metal poor. We performed a spectral analysis of early B-type stars in the galaxy, obtaining physical parameters and abundances. Our results confirm the low O-abundance of IC1613.
