Delivered to a great audience at the Farnborough Site (Cody AS). Mix of history, science, technical information and current research. Need to put it on Astrospeakers.org

Now loaded on arXiv.org Cornell University Archive. arXiv:2206.06919 [pdf, ps, other] astro-ph.SR astro-ph.EPEclipse timing variations in post-common envelope binaries: Are they a reliable indicator of circumbinary companions?Authors: D. Pulley, I. D. Sharp, J. Mallett, S. von HarrachAbstract: Post-common envelope binary systems evolve when matter is transferred from the primary star at a rate that […] Living just south of Gatwick Airport in a dark sky area still has some challenges. Trails of aircraft that get bigger and form clouds. […] Astroart 8.0 is now available from the MSB-Astroart.com Many improvements and better accuracy in some functions. All major cameras, telescopes, filter wheels and focusers are supported by Astroart. Updated plugins are released for free. Astroart is also an open system with plug-ins and development kit for C++, C#, Pascal, Visual Basic. Fully compatible […] I have missed another night of binary star measurement due to interference from Starlink. So much space pollution being caused deliberately by Elon Musk. My research could become more difficult as it will for anyone wanting to look beyond the earth. Over 11000 satellites to be launched…your joking, We only have a small percentage so far.. It wrecked my measurement of distant binary systems last night.. https://phys.org/news/2020-05-costly-collateral-elonmusk-starlink-satellite.html […] This is one of my favourite galaxies. Just did a quick exposure after doing some adjustments on my telescope. Nice plot of the light curve for HS0705+6700, 2.3hr, post-common envelope eclipsing binary system. Spectroscopy and light curve analysis indicated that the secondary companion was a low mass red dwarf star with mass and radius of 0.13M0 and 0.19R0 […] The paper is now on the archive of scientific papers: https://arxiv.org/abs/1911.00125 Quite a significant amount of new data from our group. Some interesting departures from early expectations. It will clearly take some ongoing research to identify the mechanisms that are producing some of the effects. Seems to be getting some interest! […] Yes, I did it once while I was building a new observatory. It took me just 3 hours to build!! Roll off shed design. Thick marine ply base with 6 castors to help keep it from flexing, cut out for scope pier. Even put in a dehumidifier. Mine was a bit messy as it […] |
