Simon Dawes has been busy again with his exoplanet observations for the ExoClock project. Below are his observations.
Exoplanet HAT-P-44b was discovered in 2013 by the HATNet transit survey. Its mass is 0.39 mass of Jupiter and has an orbital period of 4.3 days.
Of Exoplanet WASP -148b Simon said ”This is a 11.8 magnitude star and the dip is 8 thousandths of a magnitude – I think it must be one of the most challenging to observe with my 8″ telescope, but the conditions were obviously good and I got this fit very quickly (this is the one I said at last night’s meeting that I hadn’t submitted because I wanted to see if I could improve – this is the improved reduction) . WASP 148b is a hot Jupiter, there is another planet in this system (WASP 148c with a 35 day orbit) and the gravitational tug of the outer planet (WASP-148c) perturbs the orbit of the hot Jupiter WASP-148b”
