Five New Post-Main-Sequence Debris Disks with Gaseous Emission

Autor: Dennihy, Erik, Xu, Siyi, Lai, Samuel, Bonsor, Amy, Clemens, J. C., Dufour, Patrick, Gansicke, Boris T., Fusillo, Nicola Pietro Gentile, Hardy, Francois, Hegedus, R. J., Hermes, J. J., Kaiser, B. C., Kissler-Patig, Markus, Klein, Beth, Manser, Christopher J., Reding, Joshua S.

Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The most common end points of stellar evolution are no exception as debris d
