Absolute parameters for the F-type eclipsing binary BW Aquarii [PDF]

, 2018
BW Aqr is a bright eclipsing binary star containing a pair of F7V stars. The absolute parameters of this binary (masses, radii, etc.) are known to good precision so they are often used to test stellar models, particularly in studies of convective ...

The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star

The Astrophysical Journal
Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multiepoch spectroscopy, and recent interferometric data, confirming it as a rare ...

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

The 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.

Spectrophotometry of massive eclipsing binary stars

The Astrophysical Journal Supplement Series, 1979
Normalized flux distributions were measured for U Ophiuchi, AG Persei, lambda Tauri, and V356 Sagitarii from 1976 July to 1978 March. The spectra of lambda Tauri match those of a B4 star and an A4 star at phases 0.77--9.90, and those of a B3 star and an A4 star at other phases.

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days

The Astrophysical Journal
We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.

The Vicissitudes of the Nafs: Madness, Paralysis, and the Work of Transgression in Sufi Ethics

Anthropology of Consciousness, EarlyView.
ABSTRACT How should we theorize Sufi ethics when the practice of zikr (remembrance) that leads to spiritual enlightenment (tazkiyya) might also bring one to the brink of majzubiyat (madness)? What forms of regulation or restraint are imagined or enacted by practitioners to prevent spiritual boundlessness from perverting into its underside of paralysis (

EVOLUTIONARY EFFECTS IN CLOSE BINARIES: ANALYSIS OF THE DISTRIBUTION OF ORBITAL ECCENTRICITIES

Odessa Astronomical Publications, 2017
Dependencies of orbital eccentricity e on orbital periods P in close binary systems (CBS) of different masses and ages, being at the Main Sequence (DMS) and being eclipsing binary stars (EBS), are reviewed.

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...
