Over time, they believe the material in these dense arms become the seeds of planetary systems. Gravitational instability not only suggests how spiral arms might form, but also how planets begin to take shape far from the warmth of their sun. “We don’t completely understand how planets form,” said Isella, an assistant professor of physics and astronomy, “but we suspect there are two ways: Either small particles stick together until they form something like the Earth or Mars, or accreting gas forms a planet like Saturn or Jupiter. “But this process works only very close to the star, within a few astronomical units (roughly the distance from the sun to the Earth), because that’s where all the material is, and it has to have enough density.” Planets forming farther out, at 20-30 astronomical units, need material too, but the core accretion process is less likely, the researchers noted. “If a disk is massive enough to be gravitationally unstable, a spiral will form naturally,” Isella said Herschel online. For a given temperature, there are stars that are much more luminous than main-sequence stars. Given the dependence of luminosity on the square of the radius and the fourth power of the temperature (R2T4 of the luminosity expression above), greater luminosity implies larger radius, and such stars are termed giant star s or supergiant star s download Herschel epub.
