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!!  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 was only temporary. Cheap though! And… Fast to start up. I really liked this solution. Mrs also thought it was ok in the garden. This would be ideal for small gardens or even one of Patrick Moores concrete observatory bases. New light curve for NSVS14256825 binary.   Getting a bit low (30deg at end) Thanks for writing this handy guide.. Now in the LINKS page. Binary star measurement. Using the time variations of the eclipses we are able to calculate the orbit of possible companion objects big enough to have an effect on the orbital period of the binary pair. The picture below is the plot of light magnitude from the binary pair. The timing of this minima is then corrected for our orbit round the sun and further corrections to give the precise time of the eclipse. many of these are measured to find orbital variation caused by third objects.  A star 465 Light years away from earth. Has a planet around it that was first confirmed in 2012. So I thought I would use my observatory to look at the transit of that planet. A very small dip in the light from the star.  Unfortunately I could not get the entry into eclipse due to cloud and this makes the plot a bit distorted. This is at the exit from transit at 22:00 UTC on the 25-4-2019. |
