“This is the first strong observational proof that a Type Ia supernova can explode in a post-AGB or proto-planetary-nebula system and is an important step in understanding the origins of Type Ia supernovae,” Hsiao said. The exploding star is what is known as a Type Ia supernova, and more specifically, a member of the “super-Chandrasekhar” group. ScienceDaily. "It's still a really big deal when a supernova goes off. ... and researchers are preparing for what it will look like when the star dies in a fiery explosion called a supernova… Eventually, the star will die in a supernova explosion, but that could be another 100,000 years away. Published Aug. 7, 2020 Updated Aug. 8, ... but the fact that the supernova was such a strong explosion suggests that did not happen. Have any problems using the site? This research gives us a better understanding of the possible origins of Type Ia supernovae and will help to improve future dark energy research.". Get the latest science news with ScienceDaily's free email newsletters, updated daily and weekly. They also saw evidence that carbon monoxide was being produced. Unique supernova explosion. . Zeptoseconds: New World Record in Short Time Measurement, All-Terrain Microrobot Flips Through a Live Colon, Scientists Develop 'Mini-Brains' to Help Robots Recognize Pain and to Self-Repair, 'Universal Law of Touch' Will Enable New Advances in Virtual Reality. This supernova's characteristics -- it gets brighter extremely slowly, and it is also one of the brightest explosions in its class -- are unlike any other. Despite their importance, astronomers knew little about the origins of these supernova explosions, other than that they are the thermonuclear explosions of white dwarf stars. Last chance to join our 2020 Costa Rica Star Party! By Samantha Mathewson 16 March 2020. ScienceDaily shares links with sites in the. An image of the "Blue Snowball" planetary nebula taken with the Florida State University Observatory. "Unique supernova explosion." Florida State University. Stars go through a sort of life cycle, and these supernovae are the exploding finale of some stars with low mass. Materials provided by Florida State University. "This was a truly unique and strange event, and our explanation for it is equally interesting," said Hsiao, the paper's lead author. ... 2020 … That exploding star -- which is known as "supernova LSQ14fmg" -- was the faraway object discovered by a 37-member international research team led by Florida State University Assistant Professor of Physics Eric Hsiao.

Stars go through a sort of life cycle, and these supernovae are the exploding finale of some stars with low mass. (2020, September 10). This work was part of the Carnegie Supernova Project II, a National Science Foundation-funded program to observe supernovae. Their research, which was published in the Astrophysical Journal, helped uncover the origins of the group of supernovae this star belongs to. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. And this is our closest candidate. As a result, the neutron star should have survived. When the mass loss abruptly stopped, it created a ring of material surrounding the star.

Both isotopes are synthesized in large stars shortly before supernova explosions and are unstable, decaying completely after 4 to 15 million years. Soon after the supernova exploded, it impacted a ring of material often seen in planetary nebulae and produced the extra light and the slow brightening observed. A MYSTERIOUS gravitational wave originating near the famed … This supernova’s characteristics — it gets brighter extremely slowly, and it is also one of the brightest explosions in its class — are unlike any other. The central star was losing a copious amount of mass through a stellar wind before the mass loss was turned off abruptly and created a ring of material surrounding the star. Those observations led to their conclusion — the supernova was exploding inside what had been an asymptotic giant branch (AGB) star on the way to becoming a planetary nebula. Their research, which was published in The Astrophysical Journal, helped uncover the origins of the group of supernovae this star belongs to. Original written by Bill Wellock. Supernova Betelgeuse: ‘Blast of energy’ detected near star - Did it supernova? After collecting data with telescopes in Chile and Spain, the research team saw that the supernova was hitting some material surrounding it, which caused more light to be released along with the light from the decaying nickel. “Seeing how the observation of this interesting event agrees with the theory is very exciting,” said Jing Lu, an FSU doctoral candidate and a co-author of the paper. This research gives us a better understanding of the possible origins of Type Ia supernovae and will help to improve future dark energy research.”. They are so powerful that they shape the evolution of galaxies, and so bright that we can observe them from Earth even halfway across the observable universe. "Seeing how the observation of this interesting event agrees with the theory is very exciting," said Jing Lu, an FSU doctoral candidate and a co-author of the paper. “These supernovae can be particularly troublesome because they can mix into the sample of normal supernovae used to study dark energy. Florida State University. Other FSU researchers involved in this paper include Professor Peter Hoeflich, former postdoctoral fellow Chris Ashall, former doctoral candidate Scott Davis and doctoral candidates Sahana Kumar and Melissa Shahbandeh. Soon after the supernova exploded, it impacted a ring of material often seen in planetary nebulae and produced the extra light and the slow brightening observed. Florida State University. "This is the first strong observational proof that a Type Ia supernova can explode in a post-AGB or proto-planetary-nebula system and is an important step in understanding the origins of Type Ia supernovae," Hsiao said. The Official News Source of Florida State University, Home / News / Science & Technology / FSU-led research team discovers unique supernova explosion. One-hundred million light years away from Earth, an unusual supernova is exploding. Content on this website is for information only. The orange represents the calcium-rich material created in the explosion. They also saw evidence that carbon monoxide was being produced. Type Ia supernovae were crucial tools for discovering what’s known as dark energy, which is the name given to the unknown energy that causes the current accelerated expansion of the universe. Questions? Note: Content may be edited for style and length. That exploding star — which is known as “supernova LSQ14fmg” — was the faraway object discovered by a 37-member international research team led by Florida State University Assistant Professor of Physics Eric Hsiao. The supernova LSQ14fmg exploded in a system similar to this, with a central star losing a copious amount of mass through a stellar wind. They are so powerful that they shape the evolution of galaxies, and so bright that we can observe them from Earth even halfway across the observable universe. But the research team knew that the light from a Type Ia supernova rises and falls over the course of weeks, powered by the radioactive decay of nickel produced in the explosion. That exploding star — which is known as “supernova LSQ14fmg” — was the faraway object discovered by a 37-member international research team led by Florida State University Assistant Professor of Physics Eric Hsiao.
