How do 'Tatooine' planets survive with 2 suns?

One dwarf, main sequence star in a backwater spiral arm of the galaxy is enough; that way there is a night time where one can look at other stars and wonder, measure and research. Two stars........ IMO, the only analogy that comes to mind is: that's like having one's mother-in-law living permanently in the same house.

"Those simulations returned some scenarios where a planet managed to coexist with a pair of stars. In particular, for a planet to successfully form in this pattern, the scientists found that the system needed to start out with a fairly even rubble disk surrounding the stars. That disk also needed to be pretty circular and the pieces of planet, also known as planetesimals, need to start out about 6 miles (10 kilometers) wide or bigger."

interesting simulations that sidestep the meter barrier problem where objects do not grow to 1km or 10km diameter size planetesimals in a spinning disk. My note. The 29 page arXiv paper is https://arxiv.org/pdf/2107.11389.pdf dated 23-July-2021. The NASA ADS Abstract paper uses a total disk mass of nearly 1200 earth masses or 3.7 Mjup. "5. Results: Fiducial model...The total disk mass is 3.7MJ. We present the results for other disk models in Sect. 6." My note. The conclusion is interesting reading too. "8. Conclusions We present the first fully global coagulation-fragmentation framework for exploring planetesimal growth in S-type binary systems, such as α Cen and γ Cep. Our framework fully accounts for the specifics of planetesimal dynamics in binaries, including perturbations not only due to the eccentric stellar companion,
but also due to the gravity of the eccentric protoplanetary disk in which planetesimals orbit. We include the effects of gas drag on the eccentricity dynamics of planetesimals, as well as on their radial inspiral. Thus, this framework brings studies of planet formation in binaries to an entirely new level of realism…"
