A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission

The Astrophysical Journal Supplement Series, 2022
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%–50%, likely induced by occultations due to circumstellar disk material.

Rethinking Toleration: Wesley, Whitefield and Evangelical Collaboration in the Eighteenth Century

Journal for Eighteenth-Century Studies, EarlyView.
Abstract There is a growing body of scholarship on the history of religious toleration; nevertheless, historians have largely treated toleration as a matter of governmental policy and legal principle. This article broadens that account by examining John Wesley and George Whitefield's vision of evangelical unity across denominational lines.

Magnetospheric accretion on the T Tauri star BP Tauri [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisation signatures in photospheric lines and in narrow emission lines tracing magnetospheric accretion are monitored throughout most of the rotation cycle of BP Tau at two ...

A Model of the C iv λ λ1548, 1550 Doublet Line in T Tauri Stars

The Astrophysical Journal
The C iv doublet in the UV has long been associated with accretion in T Tauri stars. However, it is still unclear where and how the lines are formed. Here, we present a new C iv line model based on the currently available accretion shock and accretion ...

A Predicted Great Dimming of T Tauri: Has it Begun?

The Astronomical Journal
The optical star in the T Tauri triple system is the prototype of young Sun-like stars in our galaxy. This complex and dynamic system has evidence for misaligned disks and outflows, and molecular material in a circumbinary ring that obscures the southern

Family‐Led Decision‐Making Meetings as an Alternative to Initial Child Protection Conferences: Findings From a Realist Evaluation of the Safeguarding Family Group Conferencing Pilot in England

Child &Family Social Work, EarlyView.
ABSTRACT Safeguarding Family Group Conferencing (FGC) is a family‐led decision‐making process offered to some families in England as an alternative to an Initial Child Protection Conference when Children's Services have safeguarding concerns. A realist evaluation was conducted within three local authorities piloting this approach to build understanding

A Magnetically Driven Disk Wind in the Inner Disk of PDS 70

The Astrophysical Journal, 2023
PDS 70 is so far the only young disk where multiple planets have been detected by direct imaging. The disk has a large cavity when seen at submillimeter and near-infrared wavelengths, which hosts two massive planets. This makes PDS 70 the ideal target to

Can the subaltern speak through WhatsApp? Unearthing the labour/knowledge of digital methodologies

Journal of Law and Society, EarlyView.
Abstract Prompted by the challenges that Syrian refugees posed to a qualitative WhatsApp survey, this article dissects what researchers and research participants actually do when they ‘produce’ knowledge through digital methods such as WhatsApp. While many refugee participants saw the survey as an opportunity to express their views on social tensions ...
