Giant stars seen starting to merge

Two giant stars are starting to merge, astronomers say.

Sci­en­tists are re­port­ing the dis­cov­ery of a pair of huge stars that are cir­cling each oth­er and are start­ing to merge.

The­o­ret­i­cal mod­els pre­dict that the big­gest stars form by merg­ing with oth­er smaller stars, ac­cord­ing to the re­search­ers. These stars in­i­tially make up “bi­na­ry” or “mul­ti­ple” sys­tems, in which two or more stars move around each oth­er about a com­mon cen­tral point.
