Rapidly Rotating Massive Pop III stars: A Solution for High Carbon Enrichment in CEMP-no Stars
Jeena S K, Projjwal Banerjee, Gen Chiaki +1
Very metal-poor stars that have and that are enhanced in C relative to Fe () but have no enhancement of heavy elements ($[\text…
Synthetic Light Curves and Spectra from a Self-Consistent 2D Simulation of an Ultra-strippped Supernova
Thomas Maunder, Bernhard Müller, Fionntan Callan +2
Spectroscopy is an important tool for providing insights into the structure of core-collapse supernova explosions. We use the Monte Carlo radiative transfer code ARTIS to compute s…
Time-independent Simulations of Steady-State Accretion with Nuclear Burning
Kaho Tse, Alexander Heger, Ryosuke Hirai +1
We construct a new formulation that allows efficient exploration of steady-state accretion processes onto compact objects. Accretion onto compact objects is a common scenario in as…
Black holes as the end state of stellar evolution: Theory and simulations
Alexander Heger, Bernhard Müller, Ilya Mandel
The collapse of massive stars is one of the most-studied paths to black hole formation. In this chapter, we review black hole formation during the collapse of massive stars in the…
Raising the observed metallicity floor with a 3D non-LTE analysis of SDSS J102915.14+172927.9
C. Lagae, A. M. Amarsi, L. F. Rodríguez Díaz +4
Context: The first stars produced the first heavy elements and set the stage for the formation of the first galaxies. Accurate chemical abundances of ultra metal-poor stars ([Fe/H]…
Measurement of F(,)Ne reaction suggests CNO break-out in first stars
Liyong Zhang, Jianjun He, Richard J. deBoer +33
The origin of calcium production in the first stars (Pop III stars), which formed out of the primordial matter of the Big Bang, and their fates, remain most fascinating mysteries i…
