On the Long-Term Orbital Behaviour of Hilda Asteroids - I. Global Stability Patterns and Catalogue
Cristian F. Chavez, Jonathan Horner, Patryk Sofia Lykawka +2
The Hildas are objects trapped in 3:2 mean-motion resonance (MMR) with Jupiter, and are a fascinating window into the Solar system's formation and evolution. We present the results…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
HD 38973 b -- a cold Saturn orbiting a Sun-like star
Adriana Errico, Robert A. Wittenmyer, Jonathan Horner +2
We report the detection of a long-period companion to the nearby solar-type star HD\,38973 using precision radial-velocity measurements. The radial-velocity data reveal a coherent…
RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…
The California Legacy Survey V. Chromospheric Activity Cycles in Main Sequence Stars
Howard Isaacson, Andrew W. Howard, Benjamin Fulton +31
We present optical spectroscopy of 710 solar neighborhood stars collected over twenty years to catalog chromospheric activity and search for stellar activity cycles. The California…
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…
The California-Kepler Survey. XI. A Survey of Chromospheric Activity Through the Lens of Precise Stellar Properties
Howard Isaacson, Stephen R. Kane, Brad Carter +4
Surveys of exoplanet host stars are valuable tools for assessing population level trends in exoplanets, and their outputs can include stellar ages, activity, and rotation periods.…
Cool Jupiters greatly outnumber their toasty siblings: Occurrence rates from the Anglo-Australian Planet Search
Robert A. Wittenmyer, Songhu Wang, Jonathan Horner +8
Our understanding of planetary systems different to our own has grown dramatically in the past 30 years. However, our efforts to ascertain the degree to which the Solar system is a…
