Radial velocity analysis of stars with debris discs.

BISHT D. and JONES H.R.A.

Abstract (from CDS):

This study aims to identify potential exoplanet signals from nearby stars with resolved debris discs. However, the high activity of many stars with debris discs limits the detection of periodic signals. Our study is constrained to a sample of 29 stars that have appropriate radial velocity data and debris disc measurements sufficient to resolve their inclination. Our results confirm and update previous findings for exoplanets around HD 10647, HD 115617, HD 69830, GJ 581, HD 22049, and HD 142091, and we identify long-term activity signals around HD 207129 and HD 202628. We utilize the inclination angles of the debris discs, assuming co-planarity between debris disc and exoplanet orbit, to determine the 'disc-aligned' masses of radial velocity exoplanets in this study. The 'disc-aligned' masses of HD 69830 b, HD 69830 c, and 61 Vir b suggests that they may be classified as 'hot' or 'warm' Jupiters and so might be nearby examples of planets that have undergone recent type-II disc migration.
