TL;DR
This paper reports the discovery of five long-period exoplanets around nearby stars using Doppler data from Lick Observatory, highlighting their high eccentricities and confirming an independent detection of HD196885Ab.
Contribution
The study provides new long-period exoplanet detections and confirms the existence of HD196885Ab through independent observations, expanding knowledge of massive, eccentric exoplanets.
Findings
Five new long-period exoplanets discovered with high eccentricities.
Confirmation of HD196885Ab's planetary status through independent data.
Exoplanets orbit metal-rich stars, suggesting a correlation between metallicity and planet formation.
Abstract
We present time series Doppler data from Lick Observatory that reveal the presence of long-period planetary companions orbiting nearby stars. The typical eccentricity of these massive planets are greater than the mean eccentricity of known exoplanets. HD30562b has Msini = 1.29 Mjup, with semi-major axis of 2.3 AU and eccentricity 0.76. The host star has a spectral type F8V and is metal rich. HD86264b has Msini = 7.0 Mjup, arel = 2.86 AU, an eccentricity, e = 0.7 and orbits a metal-rich, F7V star. HD87883b has Msini = 1.78 Mjup, arel = 3.6 AU, e = 0.53 and orbits a metal-rich K0V star. HD89307b has Msini = 1.78 Mjup, arel = 3.3 AU, e = 0.24 and orbits a G0V star with slightly subsolar metallicity. HD148427b has Msini = 0.96 Mjup, arel = 0.93 AU, eccentricity of 0.16 and orbits a metal rich K0 subgiant. We also present velocities for a planet orbiting the F8V metal-rich binary star,…
