β Cephei Pulsators in Eclipsing Binaries Observed with TESS

open access: yesThe Astrophysical Journal Supplement Series
The combined strength of asteroseismology and empirical stellar basic parameter determinations for in-depth asteroseismic analysis of massive pulsators in eclipsing binaries shows great potential for treating the challenging and mysterious discrepancies ...

Relatability as a Racialised Construct in Corporate Graduate Recruitment: Revealing a Hidden Mechanism of Labour Market Exclusion for Black African Youth in South Africa

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT In corporate graduate recruitment worldwide, candidates are often assessed not only on competence but on whether they are deemed relatable. This study theorises relatability as a racialised cultural–affective filter that covertly sustains inequality. Drawing on qualitative interviews, we identify five interlinked processes of self‐presentation,

Producing Fraud at the Welfare‐Migration Nexus: Migrant Families and Children's Social Care

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT This article interrogates the production of ‘fraud’ at the interface between welfare and migration regimes. Taking the welfare micropublic of children's social care in the UK as a case study, we focus on encounters between migrant families subject to the ‘no recourse to public funds’ immigration condition and London local authorities.

Short-period Heartbeat Binaries from TESS Full-frame Images

open access: yesThe Astrophysical Journal Supplement Series
We identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...

The Mutable Original: How Chinese Counterfeits Become Nigerian Originals in African Markets

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Affordable Chinese copies of Western brands are ubiquitous in African markets. Despite democratizing consumer access, these goods appear to cement hegemonic value hierarchies that rank Chinese or local products as inferior to Western goods.

A Low Metallicity Massive Contact Binary Star System Candidate in WLM Identified by Hubble and James Webb Space Telescope Imaging

open access: yesThe Astrophysical Journal
We present archival Hubble Space Telescope (HST) and JWST ultraviolet through near-infrared time series photometric observations of a massive minimal-contact binary candidate in the metal-poor galaxy Wolf–Lundmark–Melotte ( Z  = 0.14 Z _⊙ ).
