The Influence of Clouds and Deuterium-burning on Brown Dwarf Habitable Zones
The Astrophysical JournalTo better understand the potential habitability of planets orbiting brown dwarfs, this work presents a new set of equilibrium temperature evolution tracks. Unlike most previous work that relied on analytic scaling relationships for brown dwarf luminosity

Listening to Hong Kong children's perspectives through pretend play
British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

JWST/NIRSpec Observations of the Coldest Known Brown Dwarf
The Astronomical Journal, 2023 We present 1–5 μ m spectroscopy of the coldest known brown dwarf, WISE J085510.83−071442.5 (WISE 0855), performed with the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST).

, 1998 After a discussion of the physical processes in brown dwarfs, we present a complete, precise definition of brown dwarfs and of planets inspired by the internal physics of objects between 0.1 and 0.001 M_sun. We discuss observational techniques for characterizing low-luminosity objects as brown dwarfs, including the use of the lithium test and cooling ...

‘I was treated as a deficit’: Immigrant teachers' career progression in Australia
British Educational Research Journal, EarlyView.Abstract Immigrant teachers have long been recruited through skilled and employer‐sponsored migration schemes to address teacher shortages in Australia, yet their career trajectories remain constrained by systemic inequities that limit their integration and professional development opportunities.

, 2002 Because of their very red colours and intrinsic faintness, field brown dwarfs will represent a small but valuable subset of the GAIA catalogue. The return of the astrometric satellite is expected to be important because of the inherent difficulty of ...

Bricks, knots, and bodies: Material encounters and the affective making of masculinity
British Educational Research Journal, EarlyView.Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...

A Large Sample of JWST/NIRSpec Brown Dwarfs: New Distant Discoveries
The Astrophysical Journal Supplement SeriesBrown dwarfs are essential probes of stellar and planetary formation, yet their low luminosities pose challenges for detection at large Galactic distances.

The direct detection of the irradiated brown dwarf in the white dwarf–brown dwarf binary SDSS J141126.20+200911.1 [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We have observed the eclipsing, post-common envelope white dwarf-brown dwarf binary, SDSS141126.20+200911.1, in the near-IR with the HAWK-I imager, and present here the first direct detection of the dark side of an irradiated brown dwarf in the $H$ band, and a tentative detection in the $K_s$ band. Our analysis of the lightcurves and indicates that the

Business Strategy and the Environment, EarlyView.ABSTRACT The role of academia in shaping the Sustainable Development Goals (SDGs) remains insufficiently understood. This study examines how SDG discourse is constructed within accounting and business research by integrating bibliometric analysis with a systematic review of 731 peer‐reviewed articles published between 2020 and 2024.
