Simulated Impact on LSST Data of Starlink V1.5 and V2 Satellites
The Astronomical JournalThe new Starlink V2 satellites incorporate improvements to the chassis brightness through dielectric mirrors, off-pointing solar arrays, and blackened exposed components. For the general case in which the reflectivities are initially unknown, we simulate
