Astronomer says 'sun-like star' may be the source of potential alien radio signal - Just The News

Description: "Wow! Signal has baffled astronomers for decades."
An astronomer claims to have significantly narrowed down the potential source of the most famous outer space radio signal, pointing toward what appears to be a star similar to our own in a distant system in the constellation Sagittarius.Amateur astronomer and YouTube host Alberto Caballero said in a paper published in the International Journal of Astrobiology that he has identified the likeliest candidate for the source of the Wow! Signal, first detected nearly 50 years ago.

The so-called Wow! signal has been a mystery since its detection in 1977. It has intrigued astronomers because it has many characteristics that might be expected in a signal from intelligent life.
Here is the paper's 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 techno-signatures. 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.
And here is a 2020 video where Caballero discusses the paper:
In contrast to the implication from the article's headline, if I understood the Abstract and video correctly, Cabellero simply asumed that a sun-like planet would be the source and identified the likeliest candidate.
The paper, An approximation to determine the source of the WOW! Signal" is available for viewing or download, and it can also be found on arXiv.
In the video, Caballero asks a question, "Do you think we should respond to the signal?" What are your thoughts on his question?

The mystery of life on other planets continues to arouse curiosity. I think, every potential let alone wow must be addressed to find answers.
I hope the aliens are found soon, I hope to greet them. I hope I meet a kind alien.😀
I think there is intelligent life, that is to say extraterrestrials, I even think that we are an experiment of them, the way in which technology advances makes me think like that, I would not respond to the signal, it is better to be distrustful
