Issue Date: | 2019 | Journal: | SCIENCE | Number: | 364 | Issue: | 6435 | First Page: | 66 | Abstract: | Many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain gaseous debris discs, visible through emission lines. We report a stable 123.4-minute periodic variation in the strength and shape of the Ca II emission line profiles originating from the debris disc around the white dwarf SDSS J122859.93+104032.9. We interpret this short-period signal as the signature of a solid-body planetesimal held together by its internal strength. | URI: | http://hdl.handle.net/20.500.12386/29207 | URL: | https://science.sciencemag.org/content/364/6435/66 https://arxiv.org/pdf/1904.02163.pdf |
