ExoGemS Detection of a Metal Hydride in an Exoplanet Atmosphere at High Spectral Resolution
The Astrophysical Journal Letters, 2023 Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs. However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in exoplanet atmospheres.

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.

Stellar and brown dwarf properties from numerical simulations
, 2010 We review the statistical properties of stars and brown dwarfs obtained from the first hydrodynamical simulation of star cluster formation to produce more than a thousand stars and brown dwarfs while simultaneously resolving the lowest mass brown dwarfs (

Mid-infrared followup of cold brown dwarfs: Diversity in age, mass and metallicity
EPJ Web of Conferences, 2011 We use Spitzer IRAC 3.6–8.0 μm photometry of late-type T dwarfs to investigate various trends which can aid the planning and interpretation of infrared (IR) surveys for the coldest T or Y dwarfs. Brown dwarfs with effective temperature (Teff)50% of their

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...

Widening participation in outward student mobility: Successes, challenges and opportunities
British Educational Research Journal, EarlyView.Abstract This article utilises data obtained through evaluation processes at Northumbria University to contribute to the emerging discourse on widening participation and outward student mobility. The rationale behind the study stems from the significant financial and non‐financial benefits associated with higher education and the UK's ongoing efforts ...

An Eccentric Brown Dwarf Eclipsing an M dwarf
The Astronomical Journal, 2022 Abstract We report the discovery of an M = 67 ± 2M J brown dwarf transiting the early M dwarf TOI-2119 on an eccentric orbit (e = 0.3362 ± 0.0005) at an orbital period of 7.200861 ± 0.000005 days. We confirm the brown dwarf nature of the transiting companion using a combination of ground-based and space-based photometry

Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Business Strategy and the Environment, EarlyView.ABSTRACT Integrating environmental sustainability (ES) into organizational strategies and operations remains a persistent challenge, particularly in fields where environmental concerns are not yet embedded within dominant institutional norms and standards of behavior. In such contexts, ES risks being overshadowed by economic and operational priorities,
