Diameters and Temperatures VII: High-angular resolution measurements of Solar-type stars with the CHARA Array
Tabetha S. Boyajian, Ashley A. Elliott, Emelly D. Tiburcio +8
We present interferometric measurements of angular diameters for 27 nearby solar-type stars obtained with the Precision Astronomical Visible Observations (PAVO) beam combiner at th…
The Scuti pulsator occurrence as a function of age, , rotation, and metallicity
Ian Berry, Daniel Huber, Yaguang Li +3
Many A- and F- type stars do not display Scuti pulsations, despite being located within the instability strip. We use photometry from the TESS Mission to discover and study …
The Pan-Pacific Planet Search -- IX. A menagerie of companions orbiting evolved stars
Robert A. Wittenmyer, Alexander Venner, Tyler Fairnington +22
We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey…
Global asteroseismology of 19,000 red giants in the TESS Continuous Viewing Zones
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
TESS (Transiting Exoplanet Survey Satellite) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19,151 r…
CHARA Interferometry and TESS Asteroseismology of the Core-Helium Burning Red Giant Cyg
Arnab Chowhan, Timothy R. Bedding, Daniel Huber +5
We present a detailed study of the secondary red clump star, Cyg, by combining long-baseline visible interferometry using the PAVO beam combiner at the CHARA Array with high-p…
The Herculis system solved after nearly three centuries
Marcus L. Marcussen, Mikkel N. Lund, Frank Grundahl +11
Herculis is a bright, nearby quadruple system. Its brightest member, Her Aa, displays solar-like oscillations, establishing the system as a crucial benchmark for asterose…
