I see that my education graphical solar system images and information, has been downloaded over 100,000 times. I am sure there are other explanations you would like to illustrate the wonders of the solar system and galaxy. Please let me know if you would like additional graphical information for your class. Also let me […]

I am pleased I met with such a friendly and mutually supportive group of fellow patients: John, Kelly, Martin …… Helped on the dark days! I have to say, all the staff in the linear accelerator team at QA hospital were great and kept our spirits up. Calm message to you all from Selsey […] Just click the link below ( please leave your review on Amazon) Hope you enjoy it: https://amzn.eu/d/9mTdBDS What a nice review from Olga Markova, 5 stars. I could not have expected more! Many thanks to Aylesbury AS for using Astrospeakers.org. It was a good evening. Mr John Mallett – Astro Speakers – Astro Speakers The lecture on technical challenges of measurement in astronomy went well and loads of interesting questions. All started from the slow (15years) of looking for exoplanets round V470 Cam. Easily visible reduction in the errors over the time I have been making measurements. Some of the error reduction techniques I have used. […] 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 […] 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 […] |
