Young Brown Dwarfs in Orion

, 2007
We have obtained optical spectra of 60 low-mass stars and brown dwarfs in Orion’s Trapezium cluster. Spectral types have been determined using a combination of narrowband indices derived from the spectra. 1. Observations Multi-object optical spectroscopy in the red region was carried out using TAURUS on the AAT and GMOS on Gemini-N on objects selected ...

From mammoth to miniature: ‘Model of a summer encampment of the Yakuts’ as a narrative object Du mammouth à la miniature : La maquette de camp d’été des Yakoutes comme objet de narration

Journal of the Royal Anthropological Institute, EarlyView.
Classic anthropological accounts of miniature objects have focused on their spatial and aesthetic dimensions, with more recent work addressing their communicative potential, connections with play, and role in protecting threatened cultural knowledge. This article analyses responses to a miniature landscape model of yhyakh, a festival celebrated in the ...

The only inflated brown dwarf in an eclipsing white dwarf–brown dwarf binary: WD1032+011B

Monthly Notices of the Royal Astronomical Society
ABSTRACT Due to their short orbital periods and relatively high-flux ratios, irradiated brown dwarfs in binaries with white dwarfs offer better opportunities to study irradiated atmospheres than hot Jupiters, which have lower planet-to-star flux ratios. WD1032+011 is an eclipsing, tidally locked white dwarf–brown dwarf binary with a 9950

Views of Vidigal: negotiating opportunities and risks in a gentrifying favela in Rio de Janeiro Favela avec vue : négocier opportunités et risques dans un quartier en voie de gentrification à Rio de Janeiro

Journal of the Royal Anthropological Institute, EarlyView.
The contested dynamics of slum gentrification in Rio de Janeiro came into focus during the brief period of relative peace brought by the pacification policy leading up to the 2016 Olympics. In this unprecedented moment, Rio's South Zone favela residents experienced a respite from the daily confrontations with police operations and drug trade violence ...
