Furthermore, the chance of stellar bodies having a binary partner increases with mass, making a double-brown-dwarf star system pretty surprising.

Based on the estimated number of binary stars in the Milky Way that roughly match this newfound system, the researchers suggest only 16 to 84 counterparts of PSR J1928+1815 and its companion may ...

The binary star system sits roughly 150 light-years from Earth. It's also incredibly heavy, with a combined mass equal to about 1.56 times that of the sun.

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its nuclear fuel and undergoes a core ...

R Aquarii belongs to a class of double stars called symbiotic stars. The primary star is an aging red giant and its companion is a compact burned-out star known as a white dwarf. The red giant ...

In binary systems, a millisecond pulsar is usually accompanied by a white dwarf: a hot, dense core left behind after a star like our Sun has exhausted its fuel. But the data Han and his colleagues ...

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. In the new study, astronomers investigated a pulsar known as PSR J1928+1815 ...
