The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
The 3D Kinematics of the Orion Nebula Cluster II: Mass-dependent Kinematics of the Inner Cluster
Lingfeng Wei, Christopher A. Theissen, Quinn M. Konopacky +3
We present the kinematic analysis of stars within $4\mbox{$^\prime$}$ from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formati…
CWISE J105512.11+544328.3: A Nearby Y Dwarf Spectroscopically Confirmed with Keck/NIRES
Grady Robbins, Aaron M. Meisner, Adam C. Schneider +17
Y dwarfs, the coolest known spectral class of brown dwarfs, overlap in mass and temperature with giant exoplanets, providing unique laboratories for studying low-temperature atmosp…
Vortex Fiber Nulling for Exoplanet Observations: Implementation and First Light
Daniel Echeverri, Jerry Xuan, Nemanja Jovanovic +31
Vortex fiber nulling (VFN) is a single-aperture interferometric technique for detecting and characterizing exoplanets separated from their host star by less than a diffracted beam…
Cosmic Evolution Early Release Science Survey (CEERS): Multi-classing Galactic Dwarf Stars in the deep JWST/NIRCam
B. W. Holwerda, Chih-Chun Hsu, Nimish Hathi +20
Low mass (sub)stellar objects represent the low end of the initial mass function, the transition to free-floating planets and a prominent interloper population in the search for hi…
On-sky speckle nulling through a single-mode fiber with the Keck Planet Imager and Characterizer
Yinzi Xin, Jerry W. Xuan, Dimitri Mawet +14
The Keck Planet Imager and Characterizer (KPIC) is an instrument at the Keck II telescope that enables high-resolution spectroscopy of directly imaged exoplanets and substellar com…
Discovery of the Exceptionally Short Period Ultracool Dwarf Binary LP 413-53AB
Chih-Chun Hsu, Adam J. Burgasser, Christopher A. Theissen
We report the detection of large-amplitude, rapid radial velocity (RV) variations and line-splitting in high-resolution Keck/NIRSPEC spectra of the M9 dwarf LP 413-53. We attribute…
Redder than Red: Discovery of an Exceptionally Red L/T Transition Dwarf
Adam C. Schneider, Adam J. Burgasser, Justice Bruursema +26
We present the discovery of CWISE J050626.96073842.4 (CWISE J05060738), an L/T transition dwarf with extremely red near-infrared colors discovered through the Backyard Worlds…
