Homogeneous planet masses I: Reanalysis of archival HARPS radial velocities
H. L. M. Osborne, L. D. Nielsen, V. Van Eylen +1
Empirical exoplanet mass-radius relations have been used to study the demographics and compositions of small exoplanets for many years. However, the heterogeneous nature of these m…
