Fresh wind blows from historical supernova

  I don't know how this would be done but I've often wished there was space .ycombinator .com (or spacetime .ycombinator .com) Since there's no tagging, maybe a specially crafted search result ie. (NASA, JAXA, IRSO, moon, satellite, space, telescope, hubble, voyager, supernova, etc.)

    That would be pretty cool actually. There is hn.algolia.com which can be used to (kind of, at least) achieve that but it's not a perfect fit. This is a result if you search "JAXA" and sort by All for the Last Year so it's just kinda there https://hn.algolia.com/?dateRange=pastYear&page=0&prefix=true&query=%22JAXA%22&sort=byDate&type=all https://hn.algolia.com/?dateRange=pastYear&page=0&prefix=tru...

  How can a remnant star be produced when the combined mass exceeds the Chandrasakar limit? It seems from the wiki that there is no actual collision. This seems to be something between a nova and a supernova. https://en.m.wikipedia.org/wiki/Type_Iax_supernova https://en.m.wikipedia.org/wiki/Type_Iax_supernova

    Presumably the explosion ejects enough material to bring the remnant below the limit. Or, possibly, rotation allows the remnant to not immediately collapse (the Chandrasekar limit is for a nonrotating body, although I understand the increase for a rapidly rotating star is only a few percent.)
