"Artist’s interpretation of HD 98800, a quadruple-star system located 150 light-years away in the constellation TW Hydrae. Bin Liu and Alejandro Vigna-Gomez suggest that the more massive tertiary-star system"

The massive triple-star system TIC 470710327 is very special. The reason for that is those stars are extremely massive. The binary stars have a combined mass of 12 times the Sun. But the third component has the mass of 16 suns.
The binary stars are orbiting each other very close. And because the third component is heavier than binary stars, that means the system is not yet stable. The binary stars might turn to orbit the third component.
Because the third component is larger. That means the TIC 470710327 is not been a triple-star system very long time. Maybe the origin of this system is in the quadruple star. In that case, another pair of those star pairs have melted together.
Or maybe, the binary star pair has impacted to heavier star's gravitational field. That explains why the heavier component is still orbiting the binary star.
The star system is made up of a binary set of stars, two stars that orbit each other, and one more massive star that orbits the binary. There are many similar star systems in the universe.
But the TIC 470710327 contains very heavy stars. And that makes it unique. Another thing that makes TIC 470710327 unique is that its third component is heavier than binary components.
This kind of stellar system is interesting even if they have probably no exoplanets. But there is always the possibility that there are some cold exoplanets outside that system. Or those exoplanets can also orbit between those stars. In that case, those planets might be burning hell. There would be no lifeforms on those planets. But they might be very interesting.
Even if planets cannot form in those solar systems there is always the possibility that the massive stars capture some rogue planets. There are calculations that many of the planets in the Milky Way are rogue planets. Those planets are formed of nova or supernova remnants after their star exploded as nova or supernova.
Or the eruption of their star pushed those planets away from their orbiter. Maybe Pluto and most of the Kuiper Belt asteroids are turning to interstellar travelers after the Sun erupted nova when it used its fuel.
