The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities

Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40

Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…

Polarization of hot Jupiter systems: a likely detection of stellar activity and a possible detection of planetary polarization

Jeremy Bailey, Kimberly Bott, Daniel V. Cotton +6

We present high-precision linear polarization observations of four bright hot Jupiter systems ( Boo, HD 179949, HD 189733 and 51 Peg) and use the data to search for polarized re…

Truly eccentric. I. Revisiting eight single-eccentric planetary systems

Robert A. Wittenmyer, Jake T. Clark, Jinglin Zhao +3

We examine eight known single-eccentric planetary systems in light of recently released large data archives and new analysis techniques. For four of these systems (HD 7449, HD 6521…

The Rotationally Modulated Polarization of Boo A

Daniel V. Cotton, Dag Evensberget, Stephen C. Marsden +9

We have observed the active star Boo A (HD 131156A) with high precision broadband linear polarimetry contemporaneously with circular spectropolarimetry. We find both signals ar…

The Pan-Pacific Planet Search VII: The most eccentric planet orbiting a giant star

Robert A. Wittenmyer, M. I. Jones, Jonathan Horner +9

Radial velocity observations from three instruments reveal the presence of a 4 M_jup planet candidate orbiting the K giant HD 76920. HD 76920b has an orbital eccentricity of 0.856$…
