The current population of benchmark brown dwarfs
The number of brown dwarfs (BDs) now identified tops 700. Yet our understanding of these cool objects is still lacking, and models are struggling to accurately reproduce observations.

Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

The Formation of Brown Dwarfs: Observations
We review the current state of observational work on the formation of brown dwarfs, focusing on their initial mass function, velocity and spatial distributions at birth, multiplicity, accretion, and circumstellar disks.

Binarity at the L/T brown dwarf transition
Current atmospheric models cannot reproduce some of the characteristics of the transition between the L dwarfs with cloudy atmospheres and the T dwarfs with dust-depleted photospheres.

Eight New Substellar Hyades Candidates from the UKIRT Hemisphere Survey
We have used the UKIRT Hemisphere Survey combined with the UKIDSS Galactic Cluster Survey, the UKIDSS Galactic Plane Survey, and the CatWISE2020 catalog to search for new substellar members of the nearest open cluster to the Sun, the Hyades.

Infrared spectra of cool stars - nature and models (Review).
Problems of modeling of IR spectra of the cool stars are discussed. Some results for M-giants, C-giants, peculiar stars and brown dwarfs are shown.

AbstractNearly 500 brown dwarfs have been discovered in recent years. The majority of these brown dwarfs exist in the solar neighborhood, yet determining their fundamental properties (mass, age, temperature & metallicity) has proved to be quite difficult, with current estimates relying heavily on theoretical models.

Sustainable Tourism and SDGs in the South Caucasus
ABSTRACT This study examines sustainable tourism practices in the South Caucasus region (Armenia, Azerbaijan, and Georgia) through the lens of the United Nations Sustainable Development Goals (SDGs). A scoping literature review was conducted, analyzing academic papers from Scopus and Web of Science databases. Content analysis and expert validation were

The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics From 10-100 AU
We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey (GPIES). This subsample includes six detected planets and three brown dwarfs; from these detections and our contrast curves we infer the ...
