The Pan-Pacific Planet Search. VIII. Complete results and the occurrence rate of planets around low-luminosity giants

Robert A. Wittenmyer, R. P. Butler, Jonathan Horner +6

Our knowledge of the populations and occurrence rates of planets orbiting evolved intermediate-mass stars lags behind that for solar-type stars by at least a decade. Some radial ve…

Recreating the OSIRIS-REx Slingshot Manoeuvre from a Network of Ground-Based Sensors

Trent Jansen-Sturgeon, Benjamin A. D. Hartig, Gregory J. Madsen +20

Optical tracking systems typically trade-off between astrometric precision and field-of-view. In this work, we showcase a networked approach to optical tracking using very wide fie…

The HD 181433 Planetary System: Dynamics and a New Orbital Solution

Jonathan Horner, Robert A Wittenmyer, Duncan J Wright +7

We present a detailed analysis of the orbital stability of the HD 181433 planetary system, finding it to exhibit strong dynamical instability across a wide range of orbital eccentr…

TESS Spots a Compact System of Super-Earths around the Naked-Eye Star HR 858

Andrew Vanderburg, Chelsea X. Huang, Joseph E. Rodriguez +48

Transiting Exoplanet Survey Satellite (TESS) observations have revealed a compact multi-planet system around the sixth-magnitude star HR 858 (TIC 178155732, TOI 396), located 32 pa…

Truly eccentric. II. When can two circular planets mimic a single eccentric orbit?

Robert A. Wittenmyer, Christoph Bergmann, Jonathan Horner +2

When, in the course of searching for exoplanets, sparse sampling and noisy data make it necessary to disentangle possible solutions to the observations, one must consider the possi…

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…
