Beta Pictoris - Knowledge (XXG)

924: 1084: 1039:, it was one of the first four stars from which such an excess was detected: these stars are called "Vega-like" after the first such star discovered. Since A-type stars like Beta Pictoris tend to radiate most of their energy at the blue end of the spectrum, this implied the presence of cool matter in orbit around the star, which would radiate at infrared wavelengths and produce the excess. This hypothesis was verified in 1984 when Beta Pictoris became the first star to have its 1707: 32: 1325: 1317: 1200: 1012: 6147: 744: 520: 1722: 39: 1072:, which passed at a distance of 3 light years about 350,000 years ago. However computer simulations favor a lower encounter velocity than either of these two candidates, which suggest that the star responsible for the rings may have been a companion star of Beta Pictoris on an unstable orbit. The simulations suggest a perturbing star with a mass of 0.5 981: 1128:

The secondary disk may be produced by a massive planet in an inclined orbit removing matter from the primary disk and causing it to move in an orbit aligned with the planet.

These particles may have been ejected from the Beta Pictoris debris disk as a result of the migration of gas giant planets within the disk and may be an indication that the Beta Pictoris system is forming an 1775:. β Pic c is at an age where planetary formations is predicted to occur via disk instability. However the planet orbits at a distance of 2.7 AU, which prediction says is too close for disk instability to occur. The low apparent magnitude, of MK = 14.3 ± 0.1, suggests that it formed via core accretion. 4404:

The observed planet by itself cannot explain the structure of the planetesimal belts at 30 AU and 52 AU from the star.

Confirmation of a second planet in the Beta Pictoris system was announced on 6 October 2020. The planet has a temperature of T = 1250 ± 50 K, a dynamical mass of M = 8.89 ± 0.75 MJup, and an age of 18.5 ± 2.5 Myr. It has an orbital period of about 1,200 days (3.3 years) and a semimajor axis of 2.7

Multiple lines of evidence suggested the existence of a massive planet orbiting in the region around 10 AU from the star: the dust-free gap between the planetesimal belts at 6.4 AU and 16 AU suggest this region is being cleared out; a planet at this distance would explain the origin of the falling
