Proxima Centauri b - may not exist

Ran across this: https://www.centauri-dreams.org/2015...-reconsidered/ I looked at Wikipedia, and found no mention of this controversy. Then I looked at the original paper, and did a search for the names of its authors... and found where on Wikipedia they are mentioned, and then checked that against the paper. It turns out that they debunked a *different* exoplanet, Alpha Centauri B b, not Proxima Centauri b. Proxima Centauri is at such a distance from Alpha Centauri that it was only recently proved that it is gravitationally bound to Alpha Centauri. Alpha Centauri B, on the other hand, orbits Alpha Centauri A at a mean distance of 23.4 AU in a highly eccentric orbit. So no doubts about the existence of Proxima Centauri b have been raised after all. John Savard |
