Astronomers learn that two white dwarfs do not make a supernova

Although every supernova has some things in common — a big boom , for example — there are plenty of unlike type . And dissimilar reasons why a superstar might go nova .

Even when focalize on one particular type of supernova , there ’s sometimes disagreement about what might be causing it . For example , it was cerebrate that supernovae of eccentric Ia had two potential parents driving them to destruction . But now , new data has allow to uranologist to narrow down likely fatherhood .

Get ready for some daytime talk show - type antics , because the August 12 consequence of Science break what kind of pervert spawn a supernova Ia. This supernova pass when a lily-white gnome , a star too low to explode on its own , is part of a binary star system . Under sure circumstances , it can cop matter from its neighbor , ramp up up enough issue to break down its centre down to critical density and make it burst forth . But what eccentric of star was letting its deadbeat fellow traveler slip all its valued matter ?

There were two competing models , both rather judgmentally named . The individual - fast modeling had the lily-white dwarf steal topic from a veritable star , like the Dominicus , or a star that had virtually exhausted its nuclear fuel but was n’t a white dwarf yet . The duple - degenerate manakin has both stars as white gnome , with one of the two being more acquisitive .

analyze the explosions from the Ia supernovae , investigator obtain telltale trace of sodium . These were not from the novae themselves , but from the gas around the supernovae . Na gas might be around reddened giants , large adept whose knocked out layers are puffed up by the intense energy give off by the fusion in the centre , but they are n’t found around compact and mostly - burnt out white nanus .

And so it seems that only a single pervert goes into forming these types of supernovae . Two lily-white nanus , the data suggest , can not make a nova .
