The chemistry and physics of these molecules are important contrib- utors to the overall evolution of the parent clouds and on the formation of the stellar systems. We review the methods and techniques through which molecules are used to probe the process of star formation. We also detail our...
Since the process of the coevolution of the sun and earth is governed by the four suggested laws of star-planet coevolution and a central mechanism of nonequivalent mass-energy exchange between the sun and planets, therefore, like the sunspot and sunspot cycle phenomena, the El Nino and La ...
The abundance of star-forming galaxies is known to decline4,5 from redshifts of about 6 to 10, but a key question is the extent of star formation at even earlier times, corresponding to the period when the first galaxies might have emerged. Here we report spectroscopic observations of MACS...
they would be born, grow, and die just like people. However, the birth of stars was still a mystery for a long time. It was not until the 1960s that astronomers discovered molecular gas in interstellar space that they had the most preliminary understanding of the evolution process of stars...
The Recent Star Formation Histories of Dwarf Galaxies in the Sculptor and M81 Groups Because they are numerous and have a wide range of properties, dwarf galaxies are useful for studying the process of star formation, the evolution of galax... BW Miller 被引量: 4发表: 1994年 Star Formation...
The star formation history of early‐type galaxies as a function of mass and environment by the environment, while the details of the process of star formation, which has built up the stellar mass, are entirely regulated by the halo mass... MS Clemens,A Bressan,B Nikolic,... - 《Monthly...

but for the initial model applied in stellar structure and evolution calculations. Our results show that the process of star formation leaves behind an imprint on the stellar structure that is potentially detectable in pulsation frequencies ofδ-Scuti stars. This opens a window to investigate early ...
At its core is HH 211-mm, a Class 0 protostar that is currently only 0.08 M⊙ in mass15 but in the process of accreting from a 0.2 M⊙ torus of gas and dust surrounding it13. Our Cycle 1 Guaranteed Time Observation programme with the National Aeronautics and Space Administration...
