ALMA measurements of mass loss and wind clumping in the massive stars of the Arches cluster

James P. Perry, Raman K. Prinja, Danielle M. Fenech +1

We present the first Atacama Large Millimeter/submillimeter Array (ALMA) Band 3 (100 GHz) and Band 6 (243 GHz) continuum observations of the Arches cluster, one of the youngest and…

First measurement of wind line formation regions in an early O-type star

D. Pauli, T. N. Parsons, R. K. Prinja

Massive stars with their strong ionizing radiation and strong stellar winds are the key feedback agents of the universe. Stellar winds of massive stars are often measured by fittin…

First spectroscopic identification of the main sequence in Westerlund 1

R. Castellanos, F. Najarro, M. Garcia +8

Being the most massive known young stellar cluster in the Milky Way, Westerlund 1 (Wd1) constitutes an ideal benchmark for understanding the evolution of massive stars. However, th…

Extensive Observational Evidence for Massive Star Stellar Wind Variability at Low Metallicities: implications for mass-loss rate determination

Timothy N. Parsons, Raman K. Prinja, Derck L. Massa +1

Mass-loss from massive stars is fundamental to stellar and galactic evolution and enrichment of the interstellar medium. Reliable determination of mass-loss rate is dependent upon…

X-Shooting ULLYSES: massive stars at low metallicity: XII. The clumped winds of O-type (super)giants in the Large Magellanic Cloud

Sarah A. Brands, Frank Backs, Alex de Koter +23

Mass loss governs the evolution of massive stars and shapes the stellar surroundings. To quantify the impact of the stellar winds we need to know the exact mass-loss rates; however…
