Turbulence-supported Massive Star Envelopes
The Astrophysical Journal Letters, 2023 Abstract The outer envelopes of massive (M ≳ 10 M ⊙) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones.

Evolution of Massive Population III Stars
Acta Polytechnica CTU Proceedings, 2014 While the evolution of massive stars in the local Universe is dominated by mass-loss, the evolution of massive Population III stars should be dominated by rotation.

Quasi-binarity of massive stars in young dense clusters - the case of the ONC
, 2007 Observations indicate that in young stellar clusters the binary fraction for massive stars is higher than for solar mass stars. For the Orion Nebula Cluster (ONC) there is a binary frequency of ~ 50% for solar-mass stars compared to 70-100% for the ...

International Astronomical Union Colloquium, 1994 AbstractSeveral topics in massive star formation are discussed. These include chemical markers of the evolutionary state of massive protostellar cores, kinematic evidence for gravitational collapse, and studies of massive star formation in different environments.

Maser, infrared and optical emission for late-type stars in the Galactic plane [PDF]
, 2017 Radio astrometric campaigns using VLBI have provided distances and proper motions for masers associated with young massive stars (BeSSeL survey). The ongoing BAaDE project plans to obtain astrometric information of SiO maser stars located in the inner ...

Hypervelocity binary stars: smoking gun of massive binary black holes
, 2007 The hypervelocity stars recently found in the Galactic halo are expelled from the Galactic center through interactions between binary stars and the central massive black hole or between single stars and a hypothetical massive binary black hole.

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 ...

Proceedings of the International Astronomical Union, 2007 AbstractMagnetic fields are unexpected in massive stars, due to the absence of a sub-surface convective dynamo. However, advances in instrumentation over the past three decades have led to their detection in a small but growing subset of these stars.

A Study of Abundance Patterns in the Sextans and Sculptor Dwarf Spheroidal Galaxies
The Astrophysical JournalIn this work, we employ a multicomponent decomposition model to study the Sextans and Sculptor dwarf spheroidal galaxies, which have distinct evolutionary histories.

Hot Stars in Stellar Populations of Galaxies
GalaxiesStar-forming galaxies are hosts of dominant populations of recently formed, hot, massive stars, which give rise to conspicuous stellar spectral features and provide the ionizing fluxes. Strong outflows of these stars shape their properties.
