HCN and C2H2 in the Atmosphere of a T8.5+T9 Brown Dwarf Binary

The Astrophysical Journal Letters
T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H _2 O, CH _4 , and NH _3 , which exhibit a wealth of absorption features in the mid-infrared.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Psychiatric Emergency Visits of Autistic Adults With or Without Documented Borderline Personality Disorder

Autism Research, EarlyView.
ABSTRACT Autism and borderline personality disorder (BPD) are each associated with increased psychiatric emergency department (PsyED) use, yet the service impact of coexisting autism–BPD remains unclear. We conducted a retrospective chart review of 1027 PsyED visits by 345 autistic adults (2018–2020) at an urban Canadian psychiatric hospital to compare
