Simulations of pre-supernova feedback in spherical clouds
Michalis Kourniotis, Richard Wünsch, Sergio Martínez-González +3
We present a one-dimensional radiation-hydrodynamic model of a spherically symmetric cloud evolving under the influence of the self-gravity and the feedback from a star cluster for…
The HST Key Project galaxies NGC 1326A, NGC 1425 and NGC 4548: New variable stars and massive star population
Z. T. Spetsieri, A. Z. Bonanos, M. Yang +2
Studies on the massive star population in galaxies beyond the Local Group are the key to understand the link between their numbers and modes of star formation in different environm…
On the evolutionary state of massive stars in transition phases in M33
M. Kourniotis, M. Kraus, M. L. Arias +2
The advanced stages of several high-mass stars are characterized by episodic mass loss shed during phases of instability. Key for assigning these stars a proper evolutionary state…
The massive star population of the Virgo Cluster galaxy NGC 4535
Z. T. Spetsieri, A. Z. Bonanos, M. Kourniotis +10
We analyzed the massive star population of the Virgo Cluster galaxy NGC 4535 using archival Hubble Space Telescope Wide Field Planetary Camera 2 images in filters F555W and F814W,…
OGLE-LMC-ECL-09937: The Most Massive Algol-Type Binary System With A Mass Measurement Accurate to 2%
D. M. Skowron, M. Kourniotis, J. L. Prieto +3
This paper presents a detailed analysis of the light and radial velocity curves of the semi-detached eclipsing binary system OGLE-LMC-ECL-09937. The system is composed of a hot, ma…
Monitoring luminous yellow massive stars in M33: new yellow hypergiant candidates
M. Kourniotis, A. Z. Bonanos, W. Yuan +3
The evolution of massive stars surviving the red supergiant (RSG) stage remains unexplored due to the rarity of such objects. The yellow hypergiants (YHGs) appear to be the warm co…
Accurate fundamental parameters and distance to a massive early-type eclipsing binary in the Danks 2 cluster
M. Kourniotis, A. Z. Bonanos, S. J. Williams +3
We present a study of the properties of the O-type, massive eclipsing binary 2MASS J13130841-6239275 located in the outskirts of the Danks 2 cluster in the G305 star-forming comple…
Variability of Massive Stars with Known Spectral Types in the Small Magellanic Cloud Using 8 Years of OGLE-III Data
M. Kourniotis, A. Z. Bonanos, I. Soszynski +10
We present a variability study of 4646 massive stars in the Small Magellanic Cloud (SMC) with known spectral types from the catalog of Bonanos et al. (2010) using the light curves…
