  Hi Folks, its been a busy month so only a few papers from September 2023 Optimized Trajectories to the Nearest Stars Using Lightweight High-velocity Photon Sails https://iopscience.iop.org/article/10.3847/1538-3881/aa813f Swarming Proxima Centauri: Optical Communication Over Interstellar Distances. https://arxiv.org/pdf/2309.07061 Earth as a Transiting Exoplanet https://arxiv.org/abs/2308.14804 A small Universe https://arxiv.org/abs/2309.03272 Earth as a Transiting Exoplanet https://arxiv.org/abs/2308.14804 ---------------------------------------------------------------------- Interesting News items Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b https://www.nasa.gov/goddard/2023/webb-discovers-methane-carbon-dioxide-in-atmosphere-of-k2-18b

  Hi Folks Please find this month’s news items and research papers below along with the attached starcharts.   If I had to pick a personal highlight it was the renewed search for a potential planet in the Juiper belt along with stars from Andromeda and exoplanets too.   Cheers Edwin       Research papers   The Dimorphos Boulder Swarm https://iopscience.iop.org/article/10.3847/2041-8213/ace1ec     How to measure light pollution—A systematic review of methods and applications https://www.sciencedirect.com/science/article/pii/S2210670723000768         On Stellar Migration from the Andromeda Galaxy https://arxiv.org/abs/2306.08143     A transiting brown dwarf in a 2 hour orbit https://arxiv.org/abs/2307.15729       The Oxygen Bottleneck for Technospheres https://arxiv.org/abs/2308.01160     Day and Night Habitability of Tidally Locked Planets with Sporadic Rotation https://arxiv.org/abs/2303.14546       Is There
