An approximation to determine the source of the WOW! Signal

Alberto Caballero

Abstract

In this paper it is analysed which of the thousands of stars in the WOW! Signal region could have the highest chance of being the real source of the signal, providing that it came from a star system similar to ours. A total of 66 G and K-type stars are sampled, but only one of them is identified as a potential Sun-like star considering the available information in the Gaia Archive. This candidate source, which is named 2MASS 19281982-2640123, therefore becomes an ideal target to conduct observations in the search for potentially habitable exoplanets. Another two candidate stars have a luminosity error interval that includes the luminosity of the Sun, and 14 candidates more are also identified as potential Sun-like stars, but the estimations on their luminosity were unknown.

    • The "paper" is here: https://arxiv.org/abs/2011.06090 but its analysis is not really something that you'd get published in an astronomy journal [speaking as a former professional astronomer]

    • I read the paper (1) and it's kind of pointless. There's no actual evidence of anything in this paper. It consists of a database search of stars in the WOW signal direction, finding one that is sort of like the Sun. It is unknown if this star even has any exoplanets. Many…
