This all changed with the first generation of stars, so bright and powerful that their light started to break apart hydrogen atoms around them, while their cores produced the elements essential for life itself.

That could be crucial to learning much more: Jupiter was likely the first planet to form around the sun, so its inner workings — particularly the nature of its core and how heat trickles out from the planet's abyssal depths — may offer hints about how other planets came to be, both in our solar system and around other stars.

Based on data taken by NASA's Chandra X-ray Observatory, the model takes into account how energy flows between two regions around the black hole — an inner core close to the boundary beyond which light can not escape (the event horizon) and an outer ring that extends far out and includes the massive young stars lurking near the black hole.

Almost all the stars in the Milky Way's disk were thought to orbit in orderly, nearly circular paths around the galaxy's core, but now astronomers find that many of the sun's neighbors have strayed from this course.

Before LIGO's detections, astronomers only had definitive observations of two varieties of black holes: ones that form from stars that were thought to top out around 20 solar masses; and, at the cores of large galaxies, supermassive black holes of still - uncertain provenance containing millions or billions of times the mass of the sun.

It spends much of its time monitoring the light from around 60 of the nearest ultracool dwarf stars and brown dwarfs («stars» which are not quite massive enough to initiate sustained nuclear fusion in their cores), looking for evidence of planetary transits.

The problem is that vast, dense clouds of dust and hundreds of millions of stars lie huddled in and around the core, obscuring the view.

The star orbits in the large galaxy are shifted to produce a ring around a compact core.

As Vega is so much bigger and hotter than Sol, however, the star will exhaust its core hydrogen after only another 650 million years or so (for a total life of around a billion years) and turn into a red giant or Cepheid variable before puffing away its outer layers to reveal a remnant core as a white dwarf.

According to Emeritus Professor Jim Kaler, Beta Hydri entered the main sequence a dwarf star at the cooler end of class F (probably around spectral class F8) but now appears to be a subgiant star that is evolving off the main sequence, as it begins to fuse increasing amounts of helium «ash» mixed with hydrogen at its core.

According to Professor Jim Kaler at the University of Illinois» Department of Astronomy, Rana started life as a main sequence F8 dwarf (somewhat hotter and brighter than Sol with slightly greater mass) around 7.5 billion years ago, but core hydrogen fusion has ceased causing the star to expand and cool as an active subgiant before becoming much brighter and larger «as a true giant star» through core helium fusion.

Then, using the Gemini North telescope, also on Hawaii, they spotted a halo of spherical clusters of stars around the galaxy's core, much like the halo that surrounds our Milky Way's core.

Such stars tend to have larger apparent motions, with rapid passages in highly inclined and elliptical orbits around the galactic core.

Abstract: From its surface properties it can be difficult to determine whether a red - giant star is in its helium - core - burning phase or only burning hydrogen in a shell around an inert helium core.

Typical size of hot cores around low - mass young stars is several tens to hundred of au, therefore the hot core in MM3 is exceptionally large.

By contrast, Hubble's measurements are based on the velocities of stars whirling around in the dense cores of globular clusters, which yield a direct measurement of the black hole masses.
