Dim Star Becomes 7 Times Hotter in 160 Seconds. Hence there would never be an inhabited planet in this system. suddenly putting out 4 to 12 times more thermal energy, even if only briefly, would fry anything resembling a planet near that star.
No time for life to develop, as it would need to be almost immune to the scorching irregular flares of the star from the word go. :) Oceans would boil, atmospheres would probably burn off, if that star has planets it must be pretty spectacular to see the energy of such a flare wash outward and turning the closest planets into glowing cinders for a brief period of time. :) A significant portion of the output of a star at 30000 Kelvin would be UV+ . Assuming planets suitable for life have an atmosphere like Earth's designed to shield against UV, X-Rays, and Gamma Rays, Planets around flare stares might not experience the 13000 times increase in total radiation that (sigma * T^4 ) suggests.

But a new analysis of the relic radiation generated by that explosive event suggests the universe got its start eons earlier and has cycled through myriad episodes of birth and death, with the Big Bang merely the most recent in a series of starting guns. That startling notion, proposed by theoretical physicist Roger Penrose of the University of Oxford in England and Vahe Gurzadyan of the Yerevan Physics Institute and Yerevan State University in Armenia, goes against the standard theory of cosmology known as inflation. The researchers base their findings on circular patterns they discovered in the cosmic microwave background, the ubiquitous microwave glow left over from the Big Bang. The circular features indicate that the cosmos itself circles through epochs of endings and beginnings, Penrose and Gurzadyan assert.

So roughly a billion years after the Big Bang, the galaxies formed around the gigantic black holes at their cores, sort of like how some snow flakes form around tiny particles of dust.
That's very interesting but these new observations open a lot of new questions. The old thinking was that stars, gas and dust at the centers of galaxies often became dense enough to form the giant holes at the cores of galaxies but this new data suggests maybe the holes were there first. How did these primordial black holes form? Do they predate the formation of the earliest stars or did they form are roughly the same time and for similar reasons? Did some other process soon after the Big Bang just "spit out" these giant holes before other large objects? This Is the Oldest Space Object Ever Found. A New Equation Reveals Our Exact Odds of Finding Alien Life. I find it beyond weird that these supposedly smart people never factor time into the equation.
If you miss someone by a minute or a millennium, you've still missed them. Even assuming a habitable world chemically, radiationally and biologically identical to Earth where evolution matched Earth's right up until the rise of humans, we still could've missed a high tech society by 100,000 years.
(Radiationally is totally a word. Now.) There's a good reason for that. So it's good to start with an assumption that we do know: Earth like conditions are necessary* but not sufficient for life. *I mean necessary in the logical sense, as in "In the presence of Earth like conditions, life can happen. " Did you miss the "L" factor is the Drake equation? A Huge Ocean Likely Covered More Than a Third of Mars 3.5 Billio.
It took NASA a few decades, several probes, and a whole lot of money to find hard evidence for the existence of water on the surface of Mars. But timing is everything. Had the agency been looking for water on the Red Planet a few billion years earlier, all they would've needed was a telescope. Voyager - The Interstellar Mission.
