Bengaluru: For the first time ever, astronomers have detected a planet in orbit around a dead star. According to findings published in the journal Nature Wednesday, a planet the size of Jupiter is in orbit around a white dwarf — the remnant after a star's death — which is 80 light years away from Earth. The planet takes merely 1.4 days to complete one orbit.

Sep 14, 2020· The uncertainties in the processes behind compact object formation imply that the fraction of BH-NS systems ejecting mass during the merger is $sim 0-9%$. In our reference we find that only $sim 0.2%$ of BH-NS mergers will have any mass ejection, and about the same percentage would produce kilonova bright enough to have a chance to be ...

Limonite - Wikipedia

Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...

Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people's attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
