He later said that "The weather was closing in, with increasing cloud, so instead of the planned practical astronomy class, I gave the students an introductory demonstration of how to use the CCD camera on one of the observatory’s automated 0.35–metre telescopes. SN2016iet is one of the best examples of a real-life pair instability supernova, and it also challenges many of the details about how these stars actually look when they explode.

[9], Early indications were that the supernova had been discovered approximately 14 days before maximum light, so it would get brighter over the following fortnight. It was the closest type Ia supernova since SN 1972E,[10] and the closest supernova of any type since 2004. SN 2014J was a type-Ia supernova in Messier 82 (the 'Cigar Galaxy', M82) discovered in mid-January 2014. Coordinates: 9h 55m 42.217s, +69° 40′ 26.56″. Symmetric group or S n; n-sphere or S n; sn (elliptic function), one of Jacobi's elliptic functions Meteorology. [10][11], Its unusual brightness and relative closeness led to SN 2014J becoming the subject of intense follow-up observations by astronomers worldwide,[6] including with the Hubble Space Telescope.

[10] The last supernova that was unambiguously closer to Earth than SN 2014J was SN 2004dj, a type II-P supernova in the galaxy NGC 2403, 8 million light-years from Earth.

[8] It was predicted to be bright enough to be visible with binoculars throughout the Northern Hemisphere. – Így add tovább! [12] Over 250 scientific papers have discussed the supernova. .tp, Országkód szerinti legfelső szintű tartomány, Sablon:Országok legfelső szintű internetes tartománynevei, Országok legfelső szintű internetes tartománynevei, Általános legfelsőbb szintű tartománynevek, https://hu.wikipedia.org/w/index.php?title=.sn&oldid=21969388, Creative Commons Nevezd meg! [17] The degree of light extinction from M82 dust blocking SN 2014J reduces its value as an observational prototype for Type Ia supernovae, but makes it a powerful probe of the interstellar medium of M82.[18]. [5], Follow-up adaptive optics observations with the 10-metre (390 in) Keck telescope at Mauna Kea Observatory, Hawaii were used to precisely determine the location of the new supernova. 3.0, A lap utolsó módosítása: 2019. november 24., 21:42. Researchers used archival images from the Hubble Space Telescope to study the environment of SN 2014J prior to the supernova, hoping to identify the progenitor system,[19] but found no identifiable progenitor star. "[5], At 19:20 GMT on 21 January 2014, Fossey and his students noticed a bright new star in their images of the galaxy Messier 82, also known as the Cigar Galaxy. šona keel, keelekood standardi ISO 639-1 järgi Central Bureau for Astronomical Telegrams, INTErnational Gamma-Ray Astrophysics Laboratory, "Near-IR Adaptive Optics Localization of PSN J09554214+6940260", "Supernova in M82 Passes Its Peak - Sky & Telescope", "Supernova in Messier 82 discovered by UCL students", "Classification of Supernova in M82 as a young, reddened Type Ia Supernova", "Prediscovery Observations of SN 2014J in M82 from the Antarctic Survey Telescope", "Bright New Supernova Blows Up in Nearby M82, the Cigar Galaxy", Centre de données astronomiques de Strasbourg, "Detection of the 847 keV gamma-ray line of radio-active Co56 from the Type Ia Supernova SN2014J in M82 with INTEGRAL", "High-resolution spectroscopy of SN2014J in M82", "Type 1a Supernovae: Why Our Standard Candle Isn't Really Standard", Timeline of white dwarfs, neutron stars, and supernovae, Monte Agliale Supernovae and Asteroid Survey, https://en.wikipedia.org/w/index.php?title=SN_2014J&oldid=982451852, Articles using Infobox astronomical event using locally defined parameters, Articles containing potentially dated statements from 2018, All articles containing potentially dated statements, Articles with unsourced statements from October 2017, Creative Commons Attribution-ShareAlike License, This page was last edited on 8 October 2020, at 07:02. [20] This is not unexpected, because the progenitors of type Ia supernovae are thought to be white dwarfs in binary systems,[21] and observation of SN 2014J provided empirical confirmation for this. [1] The first optical spectrum was obtained using the 3.5-metre (140 in) ARC telescope in New Mexico, which showed the supernova to be of Type Ia. Fossey was training four undergraduate students (Ben Cooke, Guy Pollack, Matthew Wilde and Thomas Wright) to use a small 0.35-metre (14 in) telescope at University of London Observatory, located in Mill Hill, north London. [3], SN 2014J was a popular target for amateur astronomers because it was located close to The Plough asterism (the 'Big Dipper') and visible all night for most Northern Hemisphere observers.
