The NEID Earth Twin Survey. II. Dynamical Masses in Seven High-acceleration Star Systems
Mark R. Giovinazzi, Cullen H. Blake, Paul Robertson +26
We present a set of companion dynamical masses and orbital parameters of seven star systems from the NEID Earth Twin Survey with significant absolute astrometric accelerations betw…
Three-dimensional Orbit and Dynamical Masses of GJ 105 AC
Cayla M. Dedrick, Jason T. Wright, Jason D. Eastman +11
The precision of stellar models is higher than the precision at which we are able to measure the masses of most stars, with the notable exception of binaries where we can determine…
Optimising Radial Velocity Detection Limits for Southern Habitable Worlds Observatory Targets
Robert A. Wittenmyer, Adriana Errico, Timothy R. Holt +5
The planned NASA Habitable Worlds Observatory (HWO) flagship mission aims to image and spectroscopically characterise 25 Earth-size planets in the habitable zones of their stars. H…
Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
The Search for the Inbetweeners: How packed are TESS planetary systems?
Jonathan Horner, Robert A. Wittenmyer, Stephen R. Kane +1
In this work, we examine seven systems discovered by TESS, to see whether there is any room in those systems for an additional planet (or several) to lurk unseen between the two pl…
