Supernova 1987A

Post by Christopher K. »

A group of researchers, including LSU physics professor Geoff Clayton, have published a study in Science announcing the finding of more dust around Supernova 1987A, previously undetected because it was simply too cold. This is turn has led to the group's postulating that supernovae may be the reason relatively young galaxies like the one in which Supernova 1987A resides are so dusty. In older galaxies, old stars are responsible for much of the dust, but they are not present in any appreciable number in young galaxies.

Supernova 1987A is in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The LMC is in the constellation Dorado and is therefore not visible from Baton Rouge.

This story is also being covered at NASA's Herschel site. The PI for the survey is Margaret Meixner of the Space Telescope Science Institute. One of the other investigators states this research may help understand more fully the dust in the Large Magellanic Cloud. It's good that LSU is represented in this interesting study on SN 1987A. Now if we can only find out what caused those rings!

The study of interstellar and extragalactic dust reveals much about the Milky Way's components--not just Supernova 1987a. On Friday 16 October at 7:30pm a first will occur at the Highland Road Park Observatory. Professor Geoff Clayton will present "Mysteries in Cosmic Dust". The talk has no admission fee and is aimed at a general adult audience.

Alan MacRobert has penned a new article about the 1987A event. He notes that this was the first unaided-eye supernova since the invention of the telescope.

Have we found 1987A's elusive neutron star. An image acquired by the ALMA show an off-center blob. Confirmation is still needed, but it is an exciting development.
