How Was Jupiter Formed? | Space
The core accretion model. Approximately billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump up.

limonite ore characteristics
Characteristics. Limonite is relatively dense with a specific gravity varying from to It varies in colour from a bright lemony yellow to a drab greyish brown. The streak of limonite on an unglazed porcelain plate is always brownish, a character which distinguishes it from hematite with a red streak, or from magnetite with a black streak.

Goethite: The mineral goethite information and pictures
The Mineral goethite. Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths.

2. INITIAL MASS FUNCTION AND STAR FORMATION
The final mass of the star is fixed only when accretion is halted by some feedback process. This scenario is confirmed by numerical simulations [1, 2, 3]. For example, fig. 2 shows the formation of a star cluster from an initially spherical molecular cloud with a mass of 100 M. In general, all simulations find that filamentary structures form in the initially smooth cloud before fragmenting further into stars.

One of the key phases of stellar evolution that remains poorly understood is stellar death. We lack a predictive model for how a star of a given mass explodes and what kind of remnant it leaves behind ( the initialfinal mass relation, IFMR). Progress has been limited due to the difficulty in finding and weighing black holes and neutron stars in large numbers.

Limonite
Individual minerals in limonite may form crystals, but limonite does not, although specimens may show a fibrous or microcrystalline structure, and limonite often occurs in concretionary forms or in compact and earthy masses; sometimes mammillary, botryoidal, reniform or stalactitic.

Compact star Wikipedia
All compact objects have a high mass relative to their radius, giving them a very high density, compared to ordinary atomic matter. Compact stars are often the endpoints of stellar evolution, and are in this respect also called stellar remnants. The state and type of a stellar remnant depends primarily on the mass of the star that it formed from.

Finally, the optical colors that trace recent star formation histories of the most massive group galaxies do not correlate with the Xray luminosities of the CGs, indicating that perhaps the current state of the Xray halos is independent of the recent history of stellar mass assembly in the most massive galaxies.
