- W4366999903 abstract "We report the discovery of a pair of exoplanets co-orbiting the red dwarf star GJ3470. The larger planet, GJ3470-d, was observed in a 14.9617-days orbit and the smaller planet, GJ3470-e, in a 14.9467-days orbit. GJ3470-d is sub-Jupiter size with a 1.4% depth and a duration of 3 hours, 4 minutes. The smaller planet, GJ3470-e, currently leads the larger planet by approximately 1.146-days and is extending that lead by about 7.5-minutes (JD 0.0052) per orbital cycle. It has an average depth of 0.5% and an average duration of 3 hours, 2 minutes. The larger planet, GJ3470-d, has been observed on seven separate occasions over a 3-year period, allowing for a very precise orbital period calculation. The last transit was observed by three separate observatories in Oklahoma and Arizona. The smaller planet, GJ3470-e, has been observed on five occasions over 2-years. Our data appears consistent with two exoplanets in a Horseshoe Exchange orbit. When confirmed, these will be the second and third exoplanets discovered and characterized by amateur astronomers without professional data or assistance. It will also be the first ever discovery of co-orbiting exoplanets in a Horseshoe Exchange orbit." @default.
