"Beta Pictoris is located about 60 light-years away toward the constellation of Pictor (the Painter’s Easel) and is one of the best-known examples of a star surrounded by a dusty debris disc. This image, based on data from the Digitized Sky Survey 2, shows a region of approximately 1.7 x 2.3 degrees around Beta Pictoris.

Beta Pictoris is the second-brightest star in the constellation Pictor, 63 ly from Earth. This young A-spectral-class star has three known exoplanets. Beta Pictoris b and c are large worlds. Both of those worlds have masses about 10 times Jupiter's. The exact masses of those gas giants are seen in the table.
Beta Pictoris d is farther. Its mass is about 2,5 times Jupiter's. This means this solar system seems to be upside down. Heavier planets are closer to Beta Pictoris. c is the closest. But the second one, Beta Pictoris b, is in the middle. And the last and lightest, Beta Pictoris d, is farthest.
Those exoplanets' orbital periods are: Beta Pictoris c: about 3,29 years. Beta Pictoris b: about 23,77 years. And Beta Pictoris d: about 91 or more years.
"These images trace Beta Pictoris d over more than a decade, from its discovery with ESO’s VLT to earlier detections in archival VLT and JWST data. The arrow marks the faint planet, while the brighter Beta Pictoris b appears in the upper images; the diagonal band is the system’s edge-on debris disc. Credit: ESO/B. Sutlieff, M. Bonse et al."

That means that those three massive planets are forming in a planetary system. There is lots of matter. Those large and heavy exoplanets may have very large moons. There is a material ring around Beta Pictoris. That means. Those three planets. They might not only.
Larger objects orbiting that star. The moon is an object that orbits a planet. This means those giant exoplanets. They can have large Earth-size moons. Or. Even larger orbiters. This means that those super exoplanets. They can have other gas giants orbiting them. And anyway, Beta Pictoris d is the faintest exoplanet ever found.
By using an Earth-based telescope. Beta Pictoris is too young and too hot to host habitable worlds.
“A series of images shows observations of the exoplanet Beta Pictoris d over more than a decade. (Image credit: ESO/B. Sutlieff, M. Bonse et al.”(Space.com)
“The motion of Beta Pictoris b. The orbital plane is viewed side-on; the planet is not moving towards the star.” (Wikipedia, Beta Pictoris b)
A-type star loses lots of mass. When. It turns mature. The strong hydrogen line means that the star is young. But it also shows where that star was formed.
It is a very hydrogen-rich nebula. Another interesting detail in the Beta Pictoris system is the large molecular ring around it. This dust disk is asymmetric.
Those large planets in the Beta Pictoris system. Suggest this star. Could have traveled in some interstellar nebula. Then that star is pulled into that nebula around it. The gas giant. Doesn’t necessarily mean something light. Material. Or elements that formed the planet determine its weight. The planet can be larger than Earth. But it can have weaker gravity if it is formed of very light elements. This means that an exoplanet could be very different than any planet in our solar system. Those exoplanets are so different.
That makes it impossible. To create. Some common models for planetary systems and their habitability. There are about 1,5-2 Earth-sized and Earth-mass planets in habitable zones. But most of those planets. They have no atmosphere.
Things. like megaflares or some cosmic events. They can strip that atmosphere away in seconds. Or maybe some rocky worlds. They have no such core. That. It could form the magnetic field. Without a magnetic field, plasma eruptions strip the atmosphere into space. And in the case of large stars. Those plasma eruptions. They can travel to very long distances. A normal solar wind. It can blow the atmosphere off large planets.
