This study was also the first to confirm theories about the characteristics of granules on giant stars.
The late-type giant star is a high infrared source, (6) and it is possible that this might affect the colour perception of the eye when making magnitude estimates, as of course the giant star is the primary source of light during eclipses.
Jim Fuller (Caltech) and colleagues used these changes to study a few dozen red giant stars that had been monitored for years by the Kepler spacecraft.
Burst of light Images from the Palomar Observatory in California show a giant star exploding (bottom).
However, Integral's observations revealed that a slow-spinning neutron star, with an unusually strong magnetic field has likely just begun feeding on material from a neighboring red giant star.
"No giant star had ever been discovered with copious amounts of dust in its planetary system," Melis says.
Astronomers have used a very long Chandra observation of the remnant of Kepler's supernova to deduce that the supernova was triggered by an interaction between a white dwarf and a red giant star. This is significant because another study has already shown that a so-called Type Ia supernova caused the Kepler supernova remnant.
"We infer that K3-35 is being observed at the very moment of its transformation from a giant star to a planetary nebula," the researchers say.
The red giant star Kepler-56 spins on an axis bizarrely offset by 45[degrees] from its two transiting planets, report Daniel Huber (NASA Ames Research Center) and colleagues in the October 18th Science.
The enormous W50 cloud formed when a giant star, 18,000 light years away in the constellation of Aquila, exploded as a supernova around twenty thousand years ago, sending its outer gases flying outward in an expanding bubble.
The sun is about half-way through its life in its current phase as a main sequence star, and about 5 billion years from now, it will expand into a red giant star. And eventually, that phase will end as well, and the sun will shed its outer layers, likely becoming a white dwarf in the end.
At issue, explained lead study author and doctoral student Ben Shappee, is the identity of the white dwarf's companion - is it another white dwarf, or a giant star, or even a star like our sun?
