Their computer models found if the two stars are relatively close to each other, the heat radiation from each star expands the width of the Goldilocks Zone.
This means more warmth radiates towards exoplanets from each direction, giving hope for habitable conditions to develop.
In their study, the researcher noted: “Depending on the orbit and the individual masses of the component star, the habitable zones overlap and are enlarged when the binary is at periastron – that is, the stars are closest.
“Almost all of our systems do not have overlapping habitable zones at apastron, but the habitable zone of the lower mass star is still enlarged by the flux from the higher mass star.
