Atmospheric Modeling of Brown Dwarfs
, 2023 Brown dwarfs are celestial bodies outside the solar system that are more massive than planets, but less massive than stars. Since they are less massive than stars, they do not fuse hydrogen in their core, but rather cool slowly over time.

Archaeology in Oceania, EarlyView.ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

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

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.

Brown dwarfs and giant exoplanets: bridging observations and theory with statistical methods [PDF]
, 2019 Stellar physics has been widely studied over the last century, with theoretical models for stars robustly tested by decades of observations. In contrast, studies of brown dwarfs and extra-solar giant planets were only possible for the last two decades

Between public service and market: Portraying the bifront university in a platformized world
British Educational Research Journal, EarlyView.Abstract This paper contributes to the international debate on the changes affecting recruitment and orientation processes toward higher education. Based on qualitative research involving 19 Italian public universities, the study analyses the transformations in communication, recruitment and orientation activities within platformization and increasing ...

, 2005 The formation of objects below or close to the hydrogen burning limit is currently vividly discussed and is one of the main open issues in the field of the origins of stars and planets. Applying various observational techniques, we explored a sample of brown dwarfs and very low-mass stars in the ChaI star forming cloud at an age of only a few million ...

The formation of brown dwarfs [PDF]
, 2009 We argue that brown dwarfs (BDs) and planemos form by the same mechanisms as low-mass hydrogen-burning stars, but that as one moves to lower and lower masses, an increasing fraction of these objects is formed by fragmentation of the outer parts (R xs2273

The Astrophysical JournalBrown dwarfs form the key, yet poorly understood, link between stellar and planetary astrophysics. These objects offer unique tests of Galactic structure, but observational limitations have inhibited their large-scale analysis to date. Major upcoming sky
