Understanding the formation of the first stars is one of the frontier topics in modern astrophysics and cosmology. Their emergence signalled the end of the cosmic dark ages, a few hundred million years after the Big Bang, leading to a fundamental transformation of the early Universe through the ...
Formation of the first stars 来自 EBSCO 喜欢 0 阅读量: 15 作者:Volker,Bromm 摘要: Understanding the formation of the first stars is one of the frontier topics in modern astrophysics and cosmology. Their emergence signalled the end of the cosmic dark ages, a few hundred million years after ...
We discuss the results of recent 3D simulations of first structure formation in relationship to the formation of the first stars. On the basis of a new, high-resolution AMR simulation (spatial dynamic range = 3 x 107), we conclude that the first stars are likely to be massive....
aWe will deploy the James Webb Space Telescope (JWST) to glimpse back in time to the formation of the first stars and galaxies, while our New Horizons mission will uncover knowledge about Pluto and Kuiper Belt objects in the farthest reaches of our solar system. 而我们新的天际使命在 (最远...
The origin of the supermassive black holes that inhabit the centres of massive galaxies remains unclear1,2. Direct-collapse black holes—remnants of supermassive stars, with masses around 10,000 times that of the Sun—are ideal seed candidates3,4,5,6. However, their very existence and their ...
Formation Of The First Stars And Quasars We examine various observable signatures of the first generation of stars and low--luminosity quasars, including the metal enrichment, radiation background, and dust opacity/emission that they produce. We calculate the formation history ... Z Haiman - 《...
Related to Planet formation:Herbig Ae-Be stars nebular hypothesis n. A hypothesis concerning the formation of stars and planets, and therefore the origin of the solar system, according to which a rotating nebula underwent gravitational collapse into a star with an accretion disk, from which planets...
Scientists hope to eventually observe the first stars and galaxies formed following the creation of the universe 13. 8billion years ago.The researchers are still waiting for official confirmation. “ It's possible that a few of the objects might not be galaxies, but black holes. One early ...
Probing the formation of the first low-mass stars with stellar archaeology We investigate the conditions under which the first low-mass stars formed in the Universe by confronting theoretical predictions governing the transition f... A Frebel,JL Johnson,V Bromm - 《Monthly Notices of the Royal As...
THE FORMATION OF MASSIVE STARS AND THE EFFECTSOF ROTATION ON STAR FORMATION We first review the current debates about massive star for-mation over the last decade. Then we concentrate on the accretion scenario, emphasizing the evid... A Maeder - Evry Schatzman School on Stellar Physics 被引量...
