Gray Spectral Variability in Three Brown Dwarfs Observed by HST/WFC3 Time-series Observations
The Astrophysical JournalThe L/T transition is a critical evolutionary stage for brown dwarfs and self-luminous giant planets. L/T transition brown dwarfs are more likely to be spectroscopically variable, and their high-amplitude variability probes distributions in their clouds ...

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

The Impact of Irradiation on the Radius and Thermal Evolution of Transiting Brown Dwarfs
The Astrophysical JournalMasses and radii of transiting brown dwarfs can be measured directly, in contrast to isolated field brown dwarfs, whose mass and radius inferences are model dependent.

The Astronomical Journal, 2023 We present three new brown dwarf spectral-binary candidates: CWISE J072708.09−360729.2, CWISE J103604.84−514424.4, and CWISE J134446.62−732053.9, discovered by citizen scientists through the Backyard Worlds: Planet 9 project.

, 1998 After a discussion of the physical processes in brown dwarfs, we present a complete, precise definition of brown dwarfs and of planets inspired by the internal physics of objects between 0.1 and 0.001 M_sun. We discuss observational techniques for characterizing low-luminosity objects as brown dwarfs, including the use of the lithium test and cooling ...

The Anatomical Record, EarlyView.Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

, 2002 Because of their very red colours and intrinsic faintness, field brown dwarfs will represent a small but valuable subset of the GAIA catalogue. The return of the astrometric satellite is expected to be important because of the inherent difficulty of ...

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs
The Anatomical Record, EarlyView.Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

The Influence of Clouds and Deuterium-burning on Brown Dwarf Habitable Zones
The Astrophysical JournalTo better understand the potential habitability of planets orbiting brown dwarfs, this work presents a new set of equilibrium temperature evolution tracks. Unlike most previous work that relied on analytic scaling relationships for brown dwarf luminosity
