The death of Vulcan: NEID reveals the planet candidate orbiting HD 26965 is stellar activity
Abigail Burrows, Samuel Halverson, Jared C. Siegel +17
We revisit the long-studied radial velocity (RV) target HD26965 using recent observations from the NASA-NSF 'NEID' precision Doppler facility. Leveraging a suite of classical activ…
Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System
Zhexing Li, Stephen R. Kane, Timothy D. Brandt +15
Multi-planet systems exhibit a diversity of architectures that diverge from the solar system and contribute to the topic of exoplanet demographics. Radial velocity (RV) surveys for…
Doppler Constraints on Planetary Companions to Nearby Sun-like Stars: An Archival Radial Velocity Survey of Southern Targets for Proposed NASA Direct Imaging Missions
Katherine Laliotis, Jennifer A. Burt, Eric E. Mamajek +22
Directly imaging temperate rocky planets orbiting nearby, Sun-like stars with a 6-m-class IR/O/UV space telescope, recently dubbed the Habitable Worlds Observatory, is a high prior…
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…
FIESTA II. Disentangling stellar and instrumental variability from exoplanetary Doppler shifts in Fourier domain
Jinglin Zhao, Eric B. Ford, Chris G. Tinney
The radial velocity (RV) detection of exoplanets is challenged by stellar spectroscopic variability that can mimic the presence of planets and by instrumental instability that can…
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$…
The Pan-Pacific Planet Search VI: Giant planets orbiting HD 86950 and HD 222076
Robert A. Wittenmyer, M. I. Jones, Jinglin Zhao +5
We report the detection of two new planets orbiting the K giants HD 86950 and HD 222076, based on precise radial velocities obtained with three instruments: AAT/UCLES, FEROS, and C…
Three planets orbiting Wolf 1061
D. J. Wright, R. A. Wittenmyer, C. G. Tinney +2
We use archival HARPS spectra to detect three planets orbiting the M3 dwarf Wolf1061 (GJ 628). We detect a 1.36 Mearth minimum-mass planet with an orbital period P = 4.888d (Wolf10…
