Most of these star mergers tend to be pretty equal, with both stars being of similar masses.

The stars in question are neutron stars.

This recently discovered asymmetrical binary system will merge in around 470 million years, and the gravitational influence of the larger neutron star will distort the shape of its smaller companion by stripping away large amounts of matter before they merge.

This will in turn release a larger amount of hot material than if the two stars were on equal playing fields, mass wise.

The team of researchers behind the new study believe that there is a whole population of these mismatched mergers taking place in the universe, and that they can help resolve an age old question about cosmic expansion.

Therefore, the study suggests using the gravitational waves and electromagnetic light emitted by these neutron star mergers to measure the Hubble Constant instead

The team is currently scouring the cosmos, looking for more of these odd neutron star pairings to use their explosive light as a guide
