Searching for Gas in Debris Disks
Abstract
Debris disks can be seen as the left-overs of giant planet formation and the possible nurseries of rocky planets. They were commonly understood as systems fully depleted of gas but recent gas detections in a few
debris disks suggest differently. The nature of this gas is still under debate, it could be residual or second
generation, and both possibilities have deep implications on the dust evolution and planet formation process.
In order to detect this gas, we monitore gas tracers in multi-epoch high-resolution optical spectroscopy (e.g. Kiefer et al. 2014). We have compiled a complete, unbiased database of debris disks and derived accurate disk properties for ∼ 300 of them.
