Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, Volume 95, Issue 9, Page 1616-1628, September 2026.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Subaltern Strategies and Agency: How South Asian American Youth Rework the Model Minority Stereotype
Anthropology &Education Quarterly, Volume 57, Issue 3, September 2026.ABSTRACT This study examines how South Asian American youth, as epistemically marginalized or “subaltern” actors, navigate racialized school experiences. It focuses on how South Asian American boys employ the model minority stereotype through finessing, a strategy of agency that counters exclusionary labels like perpetual foreigner and nerd while ...

Catch Me If You Can: The Dynamic Nature of Bias in Machine Learning Applications
Information Systems Journal, Volume 36, Issue 5, Page 710-742, September 2026.ABSTRACT Bias in machine learning (ML) applications represents systematic differences between expected and actual values of the predicted outputs, such that certain individuals or groups are systematically and disproportionately (dis)advantaged. This paper investigates the dynamic nature of bias in ML applications.

A Spectroscopic Study of Anomalous Stellar Populations in M67
, 2014 A population of stars exists in the old, open cluster M67, whose photometry, color magnitude diagram locations and associated evolutionary states cannot be explained by current, standard single star evolution theory. These stars are often referred to as `

Ecology of Blue Straggler Stars [PDF]
Astrophysics and Space Science Library, 2015 The existence of blue straggler stars, which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution.

Blue straggler stars in Galactic open clusters and the effect of field star contamination [PDF]
Astronomy and Astrophysics, 2008 Context: We investigate the distribution of blue straggler stars in the field of three open star clusters. Aims: The main purpose is to highlight the crucial role played by general Galactic disk fore-/back-ground field stars, which are often located in ...

CHEMICAL AND KINEMATICAL PROPERTIES OF BLUE STRAGGLER STARS AND HORIZONTAL BRANCH STARS IN NGC 6397
Astrophysical Journal, 2012 We used three sets of high-resolution spectra acquired with the multifiber facility FLAMES at the Very Large Telescope of the European Southern Observatory to investigate the chemical and kinematical properties of a sample of 42 horizontal branch (HB ...

Blue straggler stars are unique main-sequence stars that appear more luminous, hotter, and therefore younger, than their coeval counterparts. In star clusters, these stars are located above the cluster turn-off in the Hertzsprung-Russell diagram or color-

Field blue straggler stars: discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters.
