SkyMapper: A Decentralized Platform for Enhancing Planetary Science through Global Telescopic Networks Open
IntroductionSkyMapper is a pioneering platform that leverages a global network of telescopes equipped with imagers and all-sky cameras, capturing high-quality images as the primary data source. These images are used to extract photometry a…
The LUSTER Mission Concept for Lunar-Based Asteroid and Comet Monitoring Open
Introduction: We present LUSTER (LUnar-based Survey for Time-domain Exploration and Research), a proposed NASA PRISM-SALSA lunar mission to study comets, asteroids, and exoplanet atmospheres using high-cadence, dual-band photometry from th…
Faint Comet Detection with Unistellar eVscopes Open
We present eVscope observations of comets 12P/Pons-Brooks and C/2023 A3 (Tsuchinshan-ATLAS) when their magnitudes were greater than 16th magnitude. From a set of two observations of 12P taken on 2023 June 19 and 20, we measure an apparent …
The Discus Comet: C/2014 B1 (Schwartz) Open
Long-period comet C/2014 B1 (Schwartz) exhibits a remarkable optical appearance, like that of a discus or bi-convex lens viewed edgewise. Our measurements in the four years since discovery reveal a unique elongated dust coma whose orientat…
