During the Sun’s lifetime of 8 Gyr, massive stars will have enriched a few 104M⊙by many orders of magnitude if we assume an average mass of 20M⊙for each star. In that respect massive stars dominate the total energy output of galaxies as well as the energy balance in the ISM (see...
Although massive stars do not have convective interiors to generate strong magnetic fields by dynamo11, merger remnants are thought to have the requisite internal magnetic-field strengths to result in magnetars11,12. The preferential occurrence of FRBs in massive star-forming galaxies suggests that ...
<italic>Aims. </italic>We perform a comprehensive multiwavelength analysis of a sample of 20 starburst galaxies that show a substantialpopulation of Wolf-Rayet (WR) stars. In this paper, the third of the series, we present the analysis of the O and WR st
They avoid a region of high electron densities aligned with the radio source, and form stars at efficiencies that are comparable to those in normal spiral galaxies. We discuss the implications of our findings for the regulation of star formation in galaxies through AGN feedback in the absence ...
Here we report submillimetre (wavelength 870 micrometres) detections of 39 massive star-forming galaxies at z > 3, which are unseen in the spectral region from the deepest ultraviolet to the near-infrared. With a space density of about 2 × 10−5 per cubic megaparsec (two orders of ...

(Daszyńska-Daszkiewicz and Walczak2009; Moravveji2016; Paxton et al.2015; Walczak et al.2015,2019; Szewczuk and Daszyńska-Daszkiewicz2018). On the other hand, the opacity within a star is indeed lower for low-metallicity stars such as those in the SMC and LMC galaxies. This has ...
Astronomers have detected massive young stars forming in the outer part of the Scutum-Centarus Arm (OSC), the outermost portions of the galaxy.
