A Small Brown Dwarf in an Aligned Orbit Around a Young, Fully Convective M Star

The Astronomical Journal
A star's spin–orbit angle can give us insight into a system's formation and dynamical history. In this paper, we use MAROON-X observations of the Rossiter–McLaughlin effect to measure the projected obliquity of the LP 261-75 (also known as TOI-1779 ...

Does Mindfulness Support the Status Quo? The Role of Neoliberal Orientation and Emotion Regulation

European Journal of Social Psychology, EarlyView.
ABSTRACT Critiques of mindfulness as a tool embedded in neoliberal ideology have emerged since the mid‐2010s, though they remain largely theoretical. Although they suggest that mindfulness shapes a neoliberal selfhood through self‐regulation and disidentification, potentially fostering acceptance of the system and political disengagement, our research ...

Metal-Depleted Brown Dwarfs [PDF]

, 2017
This chapter reviews our current knowledge of metal-poor ultracool dwarfs with spectral types later than M7. The current census of M, L, and T subdwarfs is explored. The main colour trends of subdwarfs from the optical to the mid-infrared are described and their spectral features presented, which led to a preliminary and tentative spectral ...

Menstruation myths scale: A scale development study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The aim of this study was to develop a scale of menstruation myths. Methods The current research was conducted using a methodologic approach with a sample of 330 women who met the inclusion criteria. The scope, structural validity, and internal consistency of the scale were tested.

Physical Parameters and Properties of 20 Cold Brown Dwarfs in JWST

The Astrophysical Journal
We present a comprehensive analysis of 20 T and Y dwarfs using spectroscopy from the Near-Infrared Spectrograph (NIRSpec) CLEAR/PRISM and Mid-Infrared Instrument (MIRI) low-resolution spectrometer instruments on the James Webb Space Telescope.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

PPV Chapter - The Formation of Brown Dwarfs

, 2006
We review five mechanisms for forming brown dwarfs: (i) turbulent fragmentation of molecular clouds, producing very low-mass prestellar cores by shock compression; (ii) collapse and fragmentation of more massive prestellar cores; (iii) disc fragmentation;

Nuisance alga reduces lake partial pressure of carbon dioxide and carbon flux to the atmosphere in boreal lakes

Limnology and Oceanography, EarlyView.
Abstract Boreal lakes are generally seen as sources of carbon dioxide (CO2) to the atmosphere, even though a part of them are periodically undersaturated with CO2 and have the potential to be net‐autotrophic. This undersaturation is the result of photosynthetic activity by phytoplankton, especially flagellated species like Gonyostomum semen, which form

Analysis of a Hubble Space Telescope Search for Red Dwarfs: Limits on Baryonic Matter in the Galactic Halo

, 1995
We re-examine a deep {\it Hubble Space Telescope} pencil-beam search for red dwarfs, stars just massive enough to burn Hydrogen. The authors of this search (Bahcall, Flynn, Gould \& Kirhakos 1994) found that red dwarfs make up less than 6\% of the ...
