The effects of yields from binary massive stars as functions of metallicity
Astronomy & AstrophysicsThe evolution of massive stars in binary systems that undergo mass transfer during their lifetime is different from that of single stars. This might affect their chemical yields.

Young Massive Star Clusters [PDF]
Annual Review of Astronomy and Astrophysics, 2010 Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

The Timescales of Embedded Star Formation as Observed in STARFORGE
The Astrophysical JournalStar formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply embedded to exposed stars remain uncertain.

Supernovae from Massive Stars [PDF]
, 2017 Massive stars, by which we mean those stars exploding as core collapse supernovae, play a pivotal role in the evolution of the Universe. Therefore, the understanding of their evolution and explosion is fundamental in many branches of physics and astrophysics, among which, galaxy evolution, nucleosynthesis, supernovae, neutron stars and pulsars, black ...

Massive hybrid stars with strangeness [PDF]
Chiral Symmetry in Hadrons and Nuclei, 2014 How massive the hybrid stars could be is discussed by a "3-window model" proposed from a new strategy to construct the equation of state with hadron-quark transition. It is found that hybrid stars have a strong potentiality to generate a large mass compatible with two-solar-mass neutron star observations.

Can Dark Stars Account for the Star Formation Efficiency Excess at Very High Redshifts?
The Astrophysical JournalThe James Webb Space Telescope (JWST) has recently conducted observations of massive galaxies at high redshifts, revealing a notable anomaly in their star formation efficiency (SFE).

Massive Stars and Galactic Evolution [PDF]
Symposium - International Astronomical Union, 1991 The evolution and nucleosynthesis in massive stars are briefly reviewed, and compared with the information derived from SN1987A in LMC. Most of the theoretical models agree with the measured abundances and they can be used in models of galactic evolution.Models of chemical evolution of galaxies are presented and the role of massive stars in their ...

Wolf-Rayet stellar evolution models with improved treatment of the atmosphere
Astronomy & AstrophysicsContext. Evolutionary models of massive stars are quasi-exclusively computed using an Eddington gray atmosphere. This approximation does not accurately describe the complex physical phenomena occurring in the atmosphere of massive stars. Aims.

The Open Journal of Astrophysics, 2020 We investigate the ab-initio formation of super-massive stars in a pristine atomic cooling halo. The halo is extracted from a larger self-consistent parent simulation.
