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.

Monotonicity of the Cores of Massive Stars
The Astrophysical Journal, 2023 Abstract Massive stars are linked to diverse astronomical processes and objects including star formation, supernovae and their remnants, cosmic rays, interstellar media, and galaxy evolution. Understanding their properties is of primary importance for modern astronomy, and finding simple rules that characterize them is especially useful.

Massive Stars in the Galactic Center [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe present results of two studies aiming at better understanding the properties of massive stars in the Galactic Center. We focus on the youngest and oldest of the three massive clusters harboring this region, namely the Arches and central cluster.

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.

Models for the formation of massive stars [PDF]
, 2009 The formation of massive stars is currently an unsolved problems in astrophysics. Understanding the formation of massive stars is essential because they dominate the luminous, kinematic, and chemical output of stars. Furthermore, their feedback is likely to play a dominant role in the evolution of molecular clouds and any subsequent star formation ...

Zooming in to Massive Star Birth [PDF]
The Astrophysical Journal, 2018 Abstract We present high-resolution (0.″2, 1000 au) 1.3 mm ALMA observations of the massive infrared dark cloud clump, G028.37+00.07-C1, thought to harbor the early stages of massive star formation. Using (3–2), we resolve the previously identified C1-S core, separating the

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Signatures of Mass Segregation from Competitive Accretion and Monolithic Collapse
The Astrophysical JournalThe two main competing theories proposed to explain the formation of massive (>10 M _⊙ ) stars—competitive accretion and monolithic core collapse—make different observable predictions for the environment of the massive stars during, and immediately after,

Isolated massive star candidates in NGC 4242 with the Galaxy UV Legacy Project
Astronomy & AstrophysicsContext. There is considerable debate about the formation of massive stars, including whether a high-mass star must always form with a population of low-mass stars, or if it can also form in isolation.
