These are the latest exoplanet observations by Martin Crow.
TOI-1298 b is a gas giant exoplanet that orbits a G-type star TOI -1298 in the constellation of Ursa Minor. Its mass is 0.356 Jupiters. It takes 4.5 days to complete one orbit of its star and is 0.059 AU from its star. TOI-1298 b was discovered by the Transiting Exoplanet Survey Satellite (TESS) observatory, in 2021-09.
Martin wrote ”The observations were done as part of the ExoClock synchronous observations group. This particular transit has a depth of <5 thousandths of a magnitude!! To get useful data for this target would require a telescope diameter of at least 400mm or greater. My telescope at 235mm is too small although the dip is clearly detectable buried in the noise. The aim of the project is to combine three or more data sets from similar sized small instruments taken on the same night to increase the accuracy to that achievable with a bigger telescope. This method will help to make otherwise impossible targets viable for the majority of instruments registered on the ExoClock project.”
