Most massive planet to be transiting an M-dwarf discovered. Astronomers surprised

[gary]

In a paper submitted 30 Oct 2017 to arXiv.org, Bayliss et. al. report on
the discovery of NGTS-1b, a "hot-Jupiter" planet transiting an early
M-dwarf host every 2.67 days.

It is the most massive planet ever found orbiting a M-dwarf and has
come as a surprise to many astronomers.
