  • Disintegrating Inbound Long-period Comet C/2019 J2 
    Jewitt, David; Luu, Jane (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    We present observations of the disintegrating long-period comet C/2019 J2 (Palomar), taken to determine the nature of the object and the cause of its demise. The data are consistent with the break-up of a sub-kilometer ...
