The Astrophysical Journal Supplement SeriesNear-ultraviolet (NUV) radiation from dwarf stars plays a critical role in shaping the habitability of planetary systems, yet its long-term evolution across different spectral types remains poorly investigated.

Early star formation and the evolution of the stellar initial mass function in galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 It has frequently been suggested that the stellar IMF in galaxies was top-heavy at early times. This would be plausible physically if the IMF depends on a mass scale such as the Jeans mass that was higher at earlier times because of the generally higher temperatures that were present then. In this paper it is suggested, on the basis of current evidence

The Astrophysical JournalThe formation and evolution of planetary systems are linked to their host stellar environment. In this study, we employ a pebble-accretion-based planet population synthesis model to explore the correlation between planetary properties and stellar mass ...

Interactions between exoplanets and the winds of young stars
EPJ Web of Conferences, 2014 The topology of the magnetic field of young stars is important not only for the investigation of magnetospheric accretion, but also responsible in shaping the large-scale structure of stellar winds, which are crucial for regulating the rotation evolution

Disintegrating Multiple Systems in Early Stellar Evolution
The Astronomical Journal, 2000 An analysis of the multiplicity of 14 sources driving giant Herbig-Haro flows has revealed an observed binary frequency between 79% and 86%, of which half are higher order multiples. These sources represent the hitherto youngest sample of stars examined for binarity.

Barred Galaxies in MaNGA: Stellar Mass Dependence and Black Hole Growth
The Astrophysical JournalThis study investigates the role of internal structures, such as stellar bars and active galactic nuclei (AGN), in shaping galaxy evolution using 7408 galaxies (2641 barred) from the Sloan Digital Sky Survey IV Mapping Nearby Galaxies at Apache Point ...

Chemical Evolution of Heavy Elements in the Early Galaxy: Implications for Stellar Sources [PDF]
Publications of the Astronomical Society of Australia, 2008 AbstractAn overview of the sources for heavy elements in the early Galaxy is given. It is shown that observations of abundances in metal-poor stars can be used along with a basic understanding of stellar models to guide the search for the source of the heavy r-process nuclei (r-nuclei).

The Evolution of Substructure during Star Cluster Assembly
The Astrophysical JournalStar cluster formation and assembly occur inside filamentary and turbulent molecular clouds, which imprint both spatial and kinematic substructure on the young cluster.
