Researchers have yet to track down SDSS J1240’s binary partner but the hunt for more supernova survivors continues. Without the radioactive nickel that powers the long-lasting afterglow of the Type Ia supernovae, the explosion that sent SDSS1240+6710 hurtling across our Galaxy would have been a brief flash of light that would have been difficult to discover.
In recent years several stars have been seen to completely vanish without the trademark explosion. Scientists have spotted a white dwarf star hurtling across our galaxy after a thermonuclear explosion.

The star in question is a white dwarf called SDSS J1240+6710, which was discovered in 2015. Supernovae are powerful explosions which mark the end of a star’s life.
"In the old days, researchers would have thought a thermonuclear supernova would destroy a white dwarf entirely, but in the past 10 or 15 years, scientists have found it's possible that a partial supernova could happen that leaves part of the white dwarf behind, burned and charred," Gänsicke said. As its mass increases, the temperature and pressure within the white dwarf also increase, until nuclear fusion re-ignites at its center.
This star, called SDSS J1240+6710, was discovered in 2015 and seemed to contain neither hydrogen nor helium when it was first spotted in the sky.
The other star can be anything from a giant star to an even smaller white dwarf.
Future research could also explore whether astronomers may have already detected the brief dim flashes of light Gänsicke and his colleagues suspect are linked with this kind of strange white dwarf.
"Since they were so short, the chances were very slim to catch one, and there was very little time to follow up on whether any such detection was real. Doomed White Dwarf Stars to Spawn Supernova in Colossal Crash. Many elements found on Earth are made in the core of stars and these elements travel on to form new stars, planets and everything else in the universe. We expect that the companion stars survive the explosion, but astronomers have found little evidence of their presence, and this indicates the need for an alternative model. In a new study, scientists zeroed in on the white dwarf SDSS J1240+6710, located about 1,430 light-years from Earth. This star boasts an odd mix of oxygen, neon, magnesium, and silicon as opposed to the standard blend of predominantly hydrogen or helium with small amounts of oxygen typically seen in white dwarf stars. Eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across the galaxy. This opens up the possibility of many more survivors of supernovae travelling undiscovered through the Milky Way, according to the Warwick team.
A white dwarf is so dense that fusion sweeps rapidly out from the center, releasing the tremendous energy that blows the star apart. Their cores are mostly carbon and oxygen, which is usually surrounded by a layer of helium and then a layer of hydrogen. In this type of supernova, a white dwarf in a binary star system gains mass from its companion. The SDSSJ1240+6710 white dwarf may be the survivor of a type of supernova that hasn't yet been 'caught in the act' of explosion, the team said.
Astronomers observed a flash of ultraviolet light after a white dwarf star exploded in a supernova, marking only the second time such an event has been observed. "The explosion isn't powerful enough to totally disrupt the star.". Your email address will not be published. 'There is clearly a whole zoo out there. "That's what makes this white dwarf unique — it did undergo nuclear burning, but stopped before it got to iron," Gänsicke said.

The information is also in the black holes, NASA TV to Air News Briefing on Upcoming Spacewalk, Giant comets could pose danger to life on Earth. You will receive a verification email shortly. Researchers in this new study used the Hubble Space Telescope to take a closer look at the white dwarf and they identified carbon, sodium and aluminum in the object's atmosphere. Now that this new study suggests that smaller white dwarfs can undergo similar explosions, future models could explore how these outbursts and their subsequent remnants might look, Gänsicke said. Space photos: The most amazing images this week. There was a problem.
There is growing evidence that thermonuclear supernovae can happen under very different conditions to the Type 1a versions widely studied.
The researchers spotted signs of carbon, sodium and aluminum in its atmosphere, and its mass was found to be very small – only about 40 percent that of the Sun. "Thanks to the Gaia space mission, which was able to identify more than 50,000 white dwarf candidates, we can examine these white dwarfs to get a much better idea of what happens during these types of partial supernovas, such as what are the products of burning," Gänsicke said. 3C 397 is therefore a remnant stellar middle-aged. Could a supernova in a close binary ignite the partner? ”

These heavier elements are normally cooked up from lighter elements, and their absence in this white dwarf suggests it only went part of the way through a supernova, failing to reach the high temperatures and densities needed to forge iron-group elements.
In 1987, astronomers spotted a ‘titanic supernova’ in a nearby galaxy blazing with the power of over 100 million suns (pictured). The best studied thermonuclear supernovae are the 'Type Ia', which led to the discovery of dark energy, and are now used to map structure of the Universe. A supernova burns for only a short period of time, but it can tell scientists a lot about how the universe began. Using the Hubble Space Telescope, the scientists also identified carbon, sodium, and aluminium in the star's atmosphere, all of which are produced in the first thermonuclear reactions of a supernova. In this type of supernova, a white dwarf in a binary star system gains mass from its companion. The work was published in The Astrophysical Journal Letters.

In this study, the scientists also found that the white dwarf was traveling about 560,000 miles per hour (900,000 kilometers per hour) in the opposite direction of the way the galaxy is rotating. All the extra weight from the stolen mass squeezes the white dwarf's core, which drives the core's temperature and density high enough to set off a thermonuclear chain reaction that explosively obliterates the white dwarf.
A team of US researchers analyzed X-ray data of the supernova remnant known as 3C 397 collected by the telescope Suzaku. “Several lines of evidence indicate that both of these mechanisms produce what we call Type Ia supernovae,” said researcher Hiroya Yamaguchi, an astrophysicist at the Goddard Space Flight Center in Greenbelt NASA. The results clearly indicate the explosion of a single white dwarf, excluding the scenario well established that involves a pair of white dwarfs in coalescence. With a Bachelor of Arts in Professional Writing and several years experience under his belt, he joined New Atlas as a staff writer in 2016. Over 280,000 people receive our email newsletter. According to a new study from the University of Warwick, the white dwarf star, known by the catchy name SDSS J1240+6710, was launched away from its binary partner star in a “partial supernova.”.
“This star is unique because it has all the key features of a white dwarf but it has this very high velocity and unusual abundances that make no sense when combined with its low mass,” lead author Professor Boris Gaensicke from the Department of Physics at the University of Warwick said.

Get breaking space news and the latest updates on rocket launches, skywatching events and more! Another appears to have picked up the slack and gone supernova several times over a few decades. First of all, the star is still intact, but secondly the astronomers detected no iron, nickel, chromium or manganese, all of which should have been produced in a full-blown explosion. This isn’t the only star to disobey what we thought were the rules about supernovae. A supernova may seem like a pretty final fate, but now astronomers have discovered a star that apparently survived this explosive process. The type of supernova seen in these images, known as a Type Ia supernova, originate from a white dwarf in a close binary system accreting material from its companion star. A strange white dwarf star hurtling through the Milky Way may be the survivor of a "partial supernova," a new study finds. The findings were published in Monthly Notices of the Royal Astronomical Society. The second type of supernova occurs at the end of a single star's lifetime.
