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 […] New light curve for NSVS14256825 binary. Standard plot of mag against time. Check plot to look at a check starGetting a bit low (30deg at end) […] How to Get Started With Astronomy While on a Shoestring Budget 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 […] 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. HAT-P-12b planet Unfortunately I could not get the entry […] The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.A supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The distance to […] This is an easy one as it is an A0 spectral type. Type Ao with SA200 grating I just love this nebular. Star forming area of dust and gas. This is a better image than before Xmas. Two sets of exposures to get the core and the dust areas. Techy bit: 3 x 100sec per RGB and 4 X 130sec L merged with 3X 60sec per RGB and 4 X 60sec Luminance. […] |
