A surprise in the updated list of stellar perturbers of long period comets motion

Autor: Wysoczańska, Rita, Dybczyński, Piotr A., Polińska, Magdalena

The second Gaia data release (Gaia DR2) provided us with the precise five-parameter astrometry for 1.3 billion of sources. As stars passing close to the Solar System are thought to be responsible for influencing the dynamical history of long period c

We present results obtained from a spectroscopic analysis of high-resolution spectra taken with the ESPADONS spectrograph at the Canada-France-Hawaii Telescope and the SOPHIE spectrograph installed at the telescope in Haute-Provence Observatory. The
