Astro+ database. I. Description and first results
K. Rübke, A. Marco, I. Negueruela +4
The vast amounts of spectroscopic data for massive stars provided by previous and existing instruments on ground-based and space-based telescopes have saturated our capability to p…
Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
Hot and cool: Characterising the companions of red supergiant stars in binary systems
L. R. Patrick, I. Negueruela
In this article we study the nature of the recently identified populations of hot companions to red supergiant stars (RSGs). To this end, we compile the literature on the most well…
Astro+: Design, construction, and scientific exploitation of a large-scale massive star spectroscopic database
Klaus Rubke, Amparo Marco, Ignacio Negueruela +4
Massive stars condition the evolution of the interstellar medium by the amount of energy released during their lives and especially by their deaths as supernova explosions. The vas…
Hunting for red supergiant binaries: UVIT photometry of the SMC
L. R. Patrick, D. Thilker, D. J. Lennon +5
We present UVIT/Astrosat UV photometry of the RSG population of the Small Cloud galaxy (SMC). As RSGs are extremely faint in the far-UV, these observations directly probe potential…
