"Hot Planets" turned out to be stars
The mysterious phenomenon recently discovered by the Kepler telescope, when objects that were not large enough in mass were hotter than the parent star, were less than a week old.
Astronomers from China, Canada, USA and the UK under the leadership of Martin van Kerkveyk showed that KOI-74b, most likely, is still a white dwarf. According to the calculations of scientists, its temperature is even higher than estimated by Roe and his colleagues - about 13 thousand kelvins. However, the mass of this object is not 0.03, but 0.2 is the mass of the Sun. And there is a natural evolutionary scenario that leads to the appearance of such a hot white dwarf next to a star of class A. The case of KOI-81b is explained in approximately the same way.
