"content": "Tatsuya Akida finishing up: how do you make eccentric orbits that get super close to a WD? Asymmetric mass loss causes a \"kick\" to the WD that makes the whole planetary system eccentric. Gravity from the disk causes very efficient torques, lots of planetesimals will get very close to the WD and disrupt, adding metals to the WD that we can see with spectra.
