Atmospheric Abundances and Bulk Properties of the Binary Brown Dwarf Gliese 229Bab from JWST/MIRI Spectroscopy

The Astrophysical Journal Letters
We present JWST/Mid Infrared Instrument (MIRI) low-resolution spectroscopy (4.75–14 μ m) of the first known substellar companion, Gliese 229Bab, which was recently resolved into a tight binary brown dwarf.

Understanding sub-stellar populations using wide-field infrared surveys

EPJ Web of Conferences, 2011
This paper discusses benchmark brown dwarfs in various environments, and focuses on those in wide binary systems. We present a summary of the recently discovered T dwarf population from the UKIDSS Large Area Survey, and describe the constraints that it ...

Association of Synovial Innate Immune Exhaustion With Worse Pain in Knee Osteoarthritis

Arthritis &Rheumatology, EarlyView.
Objective Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune‐regulatory cells in pain is unknown. Our objective was to identify synovial innate immune

SDSS J100711.74+193056.2: A Candidate Common Motion Substellar Companion to the Nearest B-type Star Regulus

The Astronomical Journal
The L9 dwarf SDSS J100711.74+193056.2 is situated 7 $\mathop{.}\limits^{^\circ }$ 5 north of the nearest B-type star Regulus ( d  = 24.3 ± 0.2 pc), part of a stellar quadruplet.

The Sonora Substellar Atmosphere Models. III. Diamondback: Atmospheric Properties, Spectra, and Evolution for Warm Cloudy Substellar Objects

The Astrophysical Journal
We present a new grid of cloudy atmosphere and evolution models for substellar objects. These models include the effect of refractory cloud species, including silicate clouds, on the spectra and evolution.
