Red Supergiants in M31: The Humphreys-Davidson limit at high metallicity
Sarah L. E. McDonald, Ben Davies, Emma R. Beasor
The empirical upper limit to Red Supergiant (RSG) luminosity, known as the Humphreys-Davidson (HD) limit, has been commonly explained as being caused by the stripping of stellar en…
The temperatures of red supergiants in low metallicity environments
Gemma González-Torà, Ben Davies, Rolf-Peter Kudritzki +1
The temperatures of red supergiants (RSGs) are expected to depend on metallicity (Z) in such a way that lower-Z RSGs are warmer. In this work, we investigate the Z-dependence of th…
Red Supergiants as Cosmic Abundance Probes: massive star clusters in M83, and the mass-metallicity relation of nearby galaxies
Ben Davies, Rolf-Peter Kudritzki, Carmela Lardo +6
We present an abundance analysis of seven super-star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by Red Supergiants, and the spectral sim…
Probing the Dragonfish star-forming complex: the ionizing population of the young massive cluster Mercer 30
D. de la Fuente, F. Najarro, J. Borissova +11
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have…
Molecular gas kinematics within the central 250 pc of the Milky Way
J. D. Henshaw, S. N. Longmore, J. M. D. Kruijssen +23
Using spectral-line observations of HNCO, N2H+, and HNC, we investigate the kinematics of dense gas in the central ~250 pc of the Galaxy. We present SCOUSE (Semi-automated multi-CO…
Is the Escape Velocity in Star Clusters Linked to Extended Star Formation Histories? Using NGC 7252: W3 as a Test Case
I. Cabrera-Ziri, N. Bastian, M. Hilker +9
The colour-magnitude diagrams of some intermediate-age clusters (1-2 Gyr) star clusters show unexpectedly broad main-sequence turnoffs, raising the possibility that these clusters…
