SMDET-1: a Nearby Y Dwarf Candidate
The Backyard Worlds, :, Planet 9 Collaboration +15
We present the discovery of SMDET-1, a red, fast-moving object ("/yr) identified in time-resolved unWISE coadds using a pixel-level deep learning methodology called S…
Mitigating Charge Migration in JWST NIRISS Reveals That KELT-7 b is a Metal-enriched Ultra-hot Jupiter Orbiting a Young Metal-rich Star
Stephen P. Schmidt, Erin M. May, Joshua D. Lothringer +19
We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We…
The SPHEREx Image and Spectrophotometry Processing Pipeline
Rachel Akeson, Gregory P. Dubois-Felsmann, Brendan P. Crill +41
In this paper, we describe the SPHEREx image and spectrophotometry data processing pipeline, an infrastructure and software system designed to produce calibrated spectral images an…
The POKEMON Speckle Survey of Nearby M dwarfs. IV. Distance-Limited Catalog (POKEMON-DLC)
Catherine A. Clark, Zafar Rustamkulov, Gerard T. van Belle +5
The Solar Neighborhood is dominated by stars smaller, colder, and fainter than the Sun: the M dwarfs. If we are to understand the context in which the Sun formed and evolved, then…
SPHEREx 0.75 to 5 m Spectra for a Sequence of Nearby Brown Dwarfs
Zafar Rustamkulov, J. Kirkpatrick, Rachel Akeson +21
The SPHEREx all-sky survey has now measured the R40-100 infrared spectra of thousands of nearby brown dwarfs in the chemically rich 0.75-5 m range. The survey's wide spec…
Cloudy mornings and clear evenings on a gas giant exoplanet
Sagnick Mukherjee, David K. Sing, Guangwei Fu +25
The spectra of exoplanet atmospheres are affected by aerosols (clouds and hazes) of uncertain origin. Proposed aerosol formation mechanisms include gas condensation or photochemica…
