AKARI Observations of Brown Dwarfs I.: CO and CO_2 Bands in the Near-Infrared Spectra

, 2010
Near-infrared medium-resolution spectra of seven bright brown dwarfs are presented. The spectra were obtained with the Infrared Camera (IRC) on board the infrared astronomical satellite AKARI, covering 2.5--5.0 um with a spectral resolution of ...

Supporting the Recovery of NDIS Participants With Psychosocial Disability: A Narrative Literature Review

Australian Journal of Social Issues, EarlyView.
ABSTRACT This narrative literature review examines key issues surrounding psychosocial disability support in the National Disability Insurance Scheme (NDIS). It highlights the NDIS's neoliberal approach to support, which has underpinned a lack of clarity around the conceptualisation of psychosocial disability and recovery.

Constraints on Remnant Planetary Systems as a Function of Main-sequence Mass with HST/COS

The Astrophysical Journal
As the descendants of stars with masses less than 8 M _⊙ on the main sequence, white dwarfs provide a unique way to constrain planetary occurrence around intermediate-mass stars (spectral types BAF) that are otherwise difficult to measure with radial ...

The Insistence of Blackness and the Persistence of Antiblackness in Ireland

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

On the Orbit of the Binary Brown Dwarf Companion GL229 Ba and Bb

The Astronomical Journal
The companion GL229B was recently resolved by Xuan et al. as a tight binary of two brown dwarfs (Ba and Bb) through VLTI-GRAVITY interferometry and Very Large Telescope-CRIRES+ radial velocity (RV) measurements.

Understanding sub-stellar populations using wide-field infrared surveys

EPJ Web of Conferences, 2011
This paper discusses benchmark brown dwarfs in various environments, and focuses on those in wide binary systems. We present a summary of the recently discovered T dwarf population from the UKIDSS Large Area Survey, and describe the constraints that it ...

ULAS J141623.94$ + $134836.3 - a faint common proper motion companion of a nearby L dwarf. Serendipitous discovery of a cool brown dwarf in UKIDSS DR6

, 2010
New near-infrared large-area sky surveys (e.g. UKIDSS, CFBDS, WISE) go deeper than 2MASS and aim at detecting brown dwarfs lurking in the Solar neighbourhood which are even fainter than the latest known T-type objects, so-called Y dwarfs.

Prevalence and Factors Associated With Alleged Offending Among Children Aged 10–13 Years in the Northern Territory of Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recent policy discourse in Australia focuses on the minimum age of criminal responsibility with minimal attention to prevention strategies. Guided by theory which views child development within nested environmental contexts and recognises the cumulative impact of risk factors, this retrospective cohort study uses de‐identified linked ...
