Star ClustersWe review our present knowledge about the mass of the most luminous or very massive stars in the Magellanic Clouds (MCs). Based on high resolution data gathered during past years, we propose that stars with a present mass over 100 solar mass do not seem to exist in the MCs,...
The stellar initial mass function (IMF) is commonly interpreted to be a scale-invariant probability density distribution function (PDF) such that many small clusters yield the same IMF as one massive cluster of the same combined number of stars. Observat
less often, ablack hole. When a neutron star is created, the inside of the collapsing massive star bounces off the surface of the stellar core, reversing the implosion.
1第一篇 Eta CarinaeAs possibly the galaxy’s (银河) most massive star, Eta Carinae is now engaging in some very unusual behaviour. Australian astronomers, being in the Southern Hemisphere (半球), are able to observe it clearly. In the 19th century, Eta Carinae was for a time the third ...
The star R136a1 currently holds the record as the most massive star known to exist in theuniverse. It's more than 265 times the mass of our Sun, more than double most stars on this list. Astronomers are still trying to understand how the star can even exist. It is also the most lu...
The reason for Betelgeuse's fast-paced life is the fact that it was likely born very massive. According toScienceAlert, Betelgeuse used to be a blue-white O-type star, the most massive kind ofmain sequence, hydrogen-burning star. The bigger the star, the brighter it shines and the hotter...
By probing the rarest cosmic environments, LSST can reveal the extreme conditions under which the most luminous galaxies and the most massive supermassive black holes are formed. The gravitational lensing signals measured by LSST will enable astronomers to understand the mapping between observed galaxy ...
Stars themselves can grow to enormous sizes, with the most massive known star, R136a1, being somewhere between 265 and 315 times heavier thanour sun, which is a mind-boggling 4.4 nonillion lbs. (2 nonillion kg), or 4.4 with 30 zeroes after it. Located 130,000 light-years away in th...
When a massive star is young, it is hot, bright,and blue. Its center makes energy the same way the Sundoes. This nuclear reaction creates energy that heats thestar and makes it shine. The outflow of huge amounts ofenergy-much of it light-pushes outward from the star'scenter. But ...
This can explain the properties of the magnetic ‘blue straggler’ star τ Sco in the Upper Scorpius association that has an observationally inferred, apparent age of less than five million years, which is less than half the age of its birth association10. Such massive blue straggler stars ...
