But no, they specifically said most of them are not orbiting red dwarfs:
> Most super-Earths orbit cool dwarf stars, which are lower in mass and live much longer than the sun.
- ramraj07 4y agoWhat exactly is a cool dwarf? Doesn’t seem to be a real category - there seems to be one called ultra cool dwarves which is a subtype of red dwarf stars including TRAPPIST-1. Doesn’t exclude the tidal locking problem, but can’t confirm if they are more immune to solar variability and storms. Also apparently the planets will never be brighter than sunset in earth. The author could have at least mention some of the potential problems. I stand by calling this article disingenuous. https://en.m.wikipedia.org/wiki/TRAPPIST-1 https://en.m.wikipedia.org/wiki/TRAPPIST-1
- wahern 4y ago> they specifically said most of them are not orbiting red dwarfs: The statement, "scientists have found super-Earths orbiting 40 percent of cool dwarfs", specifically links to an article discussing red dwarfs: http://www.inaf.it/en/inaf-news/billions-of-rocky-planets-in-the-habitable-zones-around-red-dwarfs http://www.inaf.it/en/inaf-news/billions-of-rocky-planets-in... That article quotes the author of an ESO HARPS planetary survey paper: “[o]ur new observations with HARPS mean that about 40% of all red dwarf stars have a super-Earth orbiting in the habitable zone where liquid water can exist on the surface of the planet". Cool dwarfs seems to be a direct reference to red dwarfs.
