HD 715 b, a Warm Jupiter Orbiting a Massive Subgiant Discovered from a Single TESS Transit
Alexander Venner, Robert A. Wittenmyer, Andrew Vanderburg +23
Transiting Warm Jupiters orbiting bright stars are scarcely known, but a substantial number of these planets have been uncovered by the TESS mission. In this work we report the dis…
Joint RV-Astrometric Analysis of two-planet system HD 65216: Prospects for Gaia DR4
Alexander L. Wallace, Robert A. Wittenmyer, Jonathan Horner
We provide updated mass and orbital constraints on the planetary system around HD 65216, consisting of at least two giant planets on eccentric orbits. We first analyse new RV data…
Finding Alien Worlds in Queensland -- A Decade of MINERVA-Australis
Jonathan Horner, Robert A. Wittenmyer, Stephen R. Kane +2
Three decades ago, humanity entered the Exoplanet Era, with the discovery of the first planets orbiting other stars. Today, more than 6000 exoplanets are known - a tally recently b…
Hot Jupiter - Cold Jupiter: A complex sibling relation
Adriana Errico, Robert A. Wittenmyer, Jonathan Horner +2
A handful of planetary systems hosting a Hot Jupiter have been subsequently found to also host long-period giant planets. These ``cold Jupiters,'' giant planets residing beyond the…
A Near-Earth Object Model Calibrated to Earth Impactors
Sophie E. Deam, Hadrien A. R. Devillepoix, David Nesvorný +16
The population of Earth-impacting meteoroids and its size-dependent orbital elements are key to understanding the origin of meteorites and informing on planetary defence efforts. O…
The Dependence of Earth Milankovitch Cycles on Martian Mass
Stephen R. Kane, Pam Vervoort, Jonathan Horner
The Milankovitch cycles of Earth result from gravitational interactions with other bodies in the Solar System. These interactions lead to slow changes in the orbit and angular mome…
The Spin-orbit alignment of two short period eclipsing binary systems
Tony Wells, B. C. Addison, R. A. Wittenmyer +8
We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 a…
Solar System Physics for Exoplanet Research
J. Horner, S. R. Kane, J. P. Marshall +13
Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos - the dawn of the Exoplanet Era. Where once we knew of just one plane…
A BCool survey of the magnetic fields of planet-hosting solar-type stars
M. W. Mengel, S. C. Marsden, B. D. Carter +8
We present a spectropolarimetric snapshot survey of solar-type planet hosting stars. In addition to 14 planet-hosting stars observed as part of the BCool magnetic snapshot survey,…
Observing Strategies for the Detection of Jupiter Analogs
Robert A. Wittenmyer, J. Horner, R. P. Butler +6
To understand the frequency, and thus the formation and evolution, of planetary systems like our own solar system, it is critical to detect Jupiter-like planets in Jupiter-like orb…
