BETA PICTORIS PLANETS? LIFE? OR WHAT?JARAASTRONOMY 102 minute 013The ultimate question is Is there a possibility that life big businessman exist on aplanet in the Beta Pictoris trunk of rules? First, one must ask, Are there planets inthe Beta Pictoris system?. However, that question would be impossible to serviceif one did not solvent the most basic questions first Where do planets comefrom? and do the notice elements and situations, needed to form planets, exist inthe Beta Pictoris system?.To check where planets come from, one has to first look at where theplanets in our solar system came from. Does or did our star, the sun, have acircumstellar disk around it? the answer is believed to be yes.Scientists believe that a newly formed star is nowadays surrounded by arelatively dense buy of feature and dust. In 1965, A. Poveda stated, That newstars are likely to be obscured by this windbag of gas and dust (1). In 1967,Davidson and Harwit agreed with Poveda and then termed thi s occurrence, the cocoon nebula (1). different authors have referred to this occurrence as, a placental nebula (1), noting that it sustains the growth of temperamental bodies.For a long time, even before there was the term cocoon nebula, planetaryscientists knew that a cocoon nebula had surrounded the sun, long ago, in orderfor our solar system to form and take on their currents motions (1).In 1755, a German, named Immanuel Kant, intelligent that gravity wouldmake circumsolar cloud contract and that rotation would flatten it (1)." Thus,the cloud would assume the general shape of a rotating disk, explaining the factthat the planets, in our solar system, revolve in a disk-shaped distribution.This idea, about the disk-shaped nebula that was formed around the prematuresun, came to be known as the nebula hypothesis (1). Then, in 1796, a frenchmathematician named Laplace, proposed that the rotating disk continued to cooland contract, forming planetary bodies (1). Also, when inves tigating theevolution of stars, it was proposed that a star forms as a central condensationin an extensive nebula... The outer part remains behind as the cocoon nebula (1). During the very(prenominal) study it was in like manner indicated that under various conditionssuch as rotation, turbulence, etcetera the nucleus of the forming star may divideinto two or to a greater extent bodies orbiting each other (1). This may be the explanation asto wherefore more than half of all star systems are binary or multiple, rather thansingles stars, like ours, the sun.This same fragmentation may also form bodies too small to become stars.
