Study of the Ultra-Long GRB 220627A: Exploring a Possible Blue Supergiant Collapsar Origin
Ayush Garg, Amit Shukla, Dorottya Szécsi +1
Ultra-long gamma-ray bursts (ul-GRBs) challenge standard collapsar models because their extreme durations require central engines active for s. While the prompt…
Spectral characteristics of fast rotating metal-poor massive stars
Brankica Kubátová, Dorottya Szécsi
Low-metallicity massive stars are assumed to be progenitors of certain supernovae, gamma-ray bursts, and gravitational wave emitting mergers. These exotic phenomena contribute to t…
Star clusters forming in a low metallicity starburst -- rapid self-enrichment by (very) massive stars
Natalia Lahén, Thorsten Naab, Dorottya Szécsi
Stellar winds of massive () and very massive () stars may play an important role in the metal-enrichment during the format…
Modelling stellar evolution in mass-transferring binaries and gravitational-wave progenitors with METISSE
Poojan Agrawal, Jarrod Hurley, Simon Stevenson +3
Massive binaries are vital sources of various transient processes, including gravitational-wave mergers. However, large uncertainties in the evolution of massive stars, both physic…
Dust Grain Growth & Dusty Supernovae in Low-Metallicity Molecular Clouds
Sergio Martínez-González, Richard Wünsch, Guillermo Tenorio-Tagle +3
We present 3-D hydrodynamical models of the evolution of superbubbles powered by stellar winds and supernovae from young coeval massive star clusters within low metallicity ($Z = 0…
Massive stars in extremely metal-poor galaxies: A window into the past
M. Garcia, C. J. Evans, J. M. Bestenlehner +19
Cosmic History has witnessed the lives and deaths of multiple generations of massive stars, all of them invigorating their host galaxies with ionizing photons, kinetic energy, fres…
Low-metallicity massive single stars with rotation. II. Predicting spectra and spectral classes of chemically-homogeneously evolving stars
B. Kubátová, D. Szécsi, A. A. C. Sander +7
Context. Metal-poor massive stars are supposed to be progenitors of certain supernovae, gamma-ray bursts and compact object mergers, potentially contributing to the early epochs of…
The metallicity dependence of envelope inflation in massive stars
D. Sanyal, N. Langer, D. Szécsi +2
Recently it has been found that models of massive stars reach the Eddington limit in their interior, which leads to dilute extended envelopes. We perform a comparative study of the…
Searching for electromagnetic counterpart of LIGO gravitational waves in the Fermi GBM data with ADWO
Z. Bagoly, D. Szécsi, L. G. Balázs +5
The Fermi collaboration identified a possible electromagnetic counterpart of the gravitational wave event of September 14, 2015. Our goal is to provide an unsupervised data analysi…
Gamma-ray burst groups observed by BATSE, Beppo-Sax and Swift
I. Horvath, L. G Balazs, Z. Bagoly +2
Short and long bursts were identified by the BATSE team in the early 90s. A decade ago there were some suggestions about the intermediate duration type of bursts. We are going to s…
Low-metallicity massive single stars with rotation. Evolutionary models applicable to I Zwicky 18
D. Szécsi, N. Langer, S. -C. Yoon +4
Massive rotating single stars with an initial metal composition appropriate for the dwarf galaxy I Zw 18 ([Fe/H]=1.7) are modelled during hydrogen burning for initial masses of…
GRB duration distribution considering the position of the Fermi
Dorottya Szecsi, Zsolt Bagoly, Istvan Horvath +3
The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lig…
