The Dynamical Ejections of Massive Stars from Young Star Clusters [PDF]

, 2017
Massive stars form in star clusters or OB associations which may be expanded clusters. Such stars can be expelled with a high velocity from their birth cluster through a strong close encounter with other cluster members.

The Star Clusters as Links between Galaxy Evolution and Star Formation Project. I. Numerical Method

The Astrophysical Journal
Stellar clusters are critical constituents within galaxies: They are the result of highest-density star formation, and through their spatially and temporally correlated feedback, they regulate their host galaxy evolution.

Searching for GC-like abundance patterns in young massive clusters [PDF]

, 2016
Studies during the last decade have revealed that nearly all Globular Clusters (GCs) host multiple populations (MPs) of stars with a distinctive chemical patterns in light elements. No evidence of such MPs has been found so far in lower-mass ($ 10^5$ M$_{

Comparative Oligo‐FISH Mapping Illuminates Chromosomal Evolution Among Rutaceae Species Diverged Over 50 Million Years

Advanced Science, EarlyView.
Oligonucleotide‐based fluorescence in situ hybridization probes were developed in the model citrus species Citrus maxima. These probes were applied to comparative karyotyping across 14 species in the Rutaceae family. This analysis revealed chromosomal evolution in lineages that diverged from Citrus nearly 52 million years ago.

Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc

The Astrophysical Journal
The lensed Sunburst Arc ( z = 2.369) hosts a young (∼2–4 Myr), massive ( M _⋆  ∼ 10 ^7 M _⊙ ), compact ( R _eff  ∼ 8 pc) Lyman-continuum leaking super star cluster, which powers a compact (

Isolated massive star candidates in NGC 4242 with the Galaxy UV Legacy Project

Astronomy & Astrophysics
Context. 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.

Haplotype‐Resolved 3D Genomic Landscapes and Their Impacts on Agronomic Traits in Grapevine

Advanced Science, EarlyView.
This study presents a haplotype‐resolved 3D genomic landscape of grapevine, revealing that structural variations (SVs) are closely associated with phased topologically associating domain (TAD) boundary transitions. These rearrangements coordinate with allele‐specific DNA methylation (ASM) and allele‐biased gene expression (ASE) to shape key agronomic ...
