The study of the earliest stages of star formation in molecular clouds is one of the fields that should benefit most from ALMA. Improving our understanding of these deeply embedded stages is crucial to gain insight into the origin of stellar masses and binary systems. While the use of large ...

These detections establish that benzonitrile is not unique to TMC-1; rather, aromatic chemistry appears to be widespread throughout the earliest stages of star formation, probably persisting at least until the initial formation of a protostar. The abundance of benzonitrile far exceeds predictions from...
The role of magnetic fields in the early stages of star formation Magnetic fields are believed to redistribute part of the angular momentum during the collapse and could explain the order-of-magnitude difference between t... M Galametz,A Maury,V Valdivia - 《Proceedings of the International Astr...
We revisit our original papers on the burst mode of accretion by incorporating a detailed energy balance equation into a thin-disk model for the formation and evolution of circumstellar disks around low-mass protostars.Our model includes the effect of radiative cooling, viscous and shock heating,...
Learn about stellar evolution. From protostars to main sequence stars to red giants and finally to white dwarfs, neutron stars, supernovae, and black holes. Diagrams are used to plot their life cycle.
Astronomers atMITand elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation. ...
you. In reality, they change significantly — but over millions to billions of years. Stars are formed, they age and they change in cycles. By studying the life cycle of stars, you can become better acquainted with the nature of matter formation and the process our own sun is going ...
The Northern part of Great-India underwent an early rifting phase in the late Paleozoic, just at the end of the large scale Gondwanian glaciation. The begi... A Baud,V Atudorei,ZD Sharp - 《Geodinamica Acta》 被引量: 241发表: 1996年 Star Formation at Very Low Metallicity. II. On the...
“So, in short, the outcome of planet formation depends on the evolution and dispersal of the disk,” Bajaj said. At the heart of this discovery is the observation of T Cha, a young star – relative to the sun, which is about 4.6 billion years old – enveloped by an eroding circumste...
